The Educational Events of ESSCIRC ESSDERC 2021. 

The novel photo-acoustic CO2 sensor SCD4x launched by Sensirion in early 2021 represents a major innovation step in the miniaturization and cost-reduction of selective and long-term stable CO2 sensor technology. Being the first optical CO2 sensor compatible with surface-mounting technology and made for reflow soldering, the sensor allows for a broader adoption of indoor air quality monitoring both in residential air conditioning as well as internet of things devices. In my talk I will address how MEMS and CMOS technology combined with tailored assembly and packaging designs has enabled shrinking a measurement system previously reserved for scientific laboratories to an SMD component of the size smaller than a sugar cube.

Breaking the size barrier in CO2 sensing: the photo-acoustic CO2 sensor “SCD4x”

In recent years, an enormous surge of works is being carried out on developing new methods for magnetic devices for various kinds of healthcare applications. Miniaturising magnetic sensors offer the prospect to replace the bulky laboratory instruments with easy-to-use clinical platforms ranging from portable lab-on-a-chip diagnostics to wearable and implantable devices. It would bring down the cost, size and out-of-hospital use by several orders of magnitude. Implementation of such magnetic sensing microsystems using traditional CMOS technology is inefficient in terms of area, sensitivity and signal to noise ratio. Such inefficiencies have driven a significant effort to investigate the development of beyond-CMOS devices. Integration of magnetoresistive devices, e.g. Tunnelling Magnetoresistive (TMR), with CMOS technology provides an opportunity to produce and optimise powerful and low-power devices for low biomagnetic field applications. Such heterogeneously structure combining the CMOS circuitry interface and non-CMOS sensors higher performance electronics for detecting pico-Tesla magnetic field. 
The talk will introduce our research at the Microelectronics Lab (www.melabresearch.com) at the University of Glasgow on integrated electronic circuits and sensors with several different works addressing the development of architectures for the implementation of efficient biomedical wearable and implantable technologies. It presents findings and trends in magnetic sensing devices, including:
(i) Tunnelling magnetoresistive (TMR) sensors and circuit Interfaces for malaria parasite detection
(ii) Integrated micro–Nuclear Magnetic Resonance (micro-NMR) for point of care diagnostics
(iii) Implantable Magnetomyography (MMG) with magnetoelectric (ME) and TMR sensors 
(iv) Spintronic sensors based on Magnetic Tunnel Junction for wearable eye movements monitoring


Principles of Magnetic Sensing in Medical Microsystems

In less than a decade, optical sensing has become a key topic because of the growing potential in spectroscopy, chemical and biomolecular sensing, security and industry applications. This talk presents recent results on the chip level integration of the building blocks for chemical detection.

Challenges and Opportunities in the Miniaturization of the Optical Sensing

Photoplethysmography (PPG) is a non-invasive optical recording method to measure a number of vital signs in a very unobtrusive manner. While PPG has been employed in a clinical setting already for a few decades, it has regained popularity in the last decade specifically for wearable health applications. This talk will discuss the latest-state-of-the-art on ASIC readout architectures for low-power, high performance PPG readout circuits.

Photoplethysmography (PPG) readout interface circuit design techniques

Brain-machine interfaces (BMIS) of the future will be used to treat neurological disorders for which a cure does not exist yet. For this futuristic view to become a reality, we must overcome many technological challenges. A major goal is to increase the number of neurons that we can simultaneously interact with. To do so, future systems will record from more than a thousand channels at the same time. These systems will create a massive amount of raw data that needs to be compressed on the implant to lower the power consumption of the wireless link. As custom signal specifications for BMI applications become clearer and are diverging from those needed for basic neuroscience, there is an opportunity for application-specific lossy compression that improves further the power efficiency of these implants. In this workshop, we will cover the basic aspects of compression for BMIs and describe two different compression schemes for a motor BMI and an artificial retina.

Near-sensor compression in high-bandwidth brain-computer interface

Three key challenges in the design of modern closed-loop neurostimulators for the treatment of neurological disorders, such as intractable epilepsy, are discussed. The first challenge is the need for the best possible efficacy by implementing neuromodulation therapies that are custom-tailored for each patient. Here, the question of where to employ machine learning, whether within the medical device or remotely is addressed, with two energy-efficient implementation examples given: a long-effective-memory SVM and a spatiotemporal CNN. The second challenge is a clear patients’ preference for lower invasiveness – two methods are presented that enable selective recruitment of nerves by decomposing the stimulus signal as it is being delivered to the target. This allows to break the trade-off between invasiveness and selectivity, but requires complex stimulation waveforms applied concurrently with the neural activity recording. As a result, the third challenge is the need for tolerance to stimulation artifacts. Delta-sigma quantization techniques to track fast input transients, by adapting DAC step size, ADC reference voltage and ADC clock frequency, are presented to address this challenge.

Artificially-intelligent Closed-loop Neurostimulators for the Treatment of Neurological Disorders

In this talk, we present emerging technologies for implantable CMOS optoelectronics for interfacing to the brain.

Implantable Optoelectronics for Neural Interfaces

Commercial 5G services have been launched globally. Study and development for technologies toward the evolution of 5G are ongoing, taking into account issues in early 5G services and emerging market needs. In parallel, research focused on technologies and services beyond 5G and 6G is accelerating throughout the world. This presentation will explain NTT DOCOMO's views and our latest activities on 5G evolution and 6G.

5G evolution and 6G: benefits and challenges

In this talk, power amplifier MMICs developed for emerging D-band (110-170 GHz) wireless communication links using InP DHBT technology will be presented. Power amplifiers designed for millimeter-wave frequencies in general suffer from low gain of the transistors and high loss in the interconnect structures. To complicate matters, it is foreseen that higher order modulation formats will be employed to enhance the spectral efficiency in future mm-wave wireless communication links and this dictates strict linearity requirements to the power amplifiers. 
The talk will describe circuit topologies able to exhaust the potential of the InP DHBT technology used and present a low-loss interconnect strategy suitable for the implementation of matching networks and power combining structures. The experimental results of implemented D-band power amplifier MMICs will be presented.

InP DHBT based Power Amplifiers for D-band (110 – 170 GHz) Wireless Communication Links

High data rate communications and high bandwidth communication and sensing systems demand for wideband MMIC operating over a bandwidth with excess of 100 GHz. This talk will introduce such MMICs and their design and characterization challenges. The talk will focus on the widest bandwidth and bandwidth limits as well as the achievable output power, noise figure and gain, as well as constant time delay versus frequency of operation. FBH has demonstrated > 150 GHz bandwidth with output power levels > 12 dBm and concurrent noise-figures of < 9 dB, which allow for robust wideband receive modules and high power transmit modules. Results will also be shown on signal switches and preliminary results on wideband mixers. Routes towards even large bandwidths will be discussed and improvement in output power will be outlined.
