**Abstract:**

This paper presents dual-layer proton irradiation profile to improve the thermal stability of high-resistivity substrate formed by low-fluence proton irradiation. Dual-layer irradiation uses targeted irradiation to the Si-SiO2 interface to reduce the fluence required for preventing the formation of conduction layer after annealing. Thermal stability of effective substrate resistivity is evaluated indirectly through inductor Q-factor measurement before and after annealing at 260°C for 1 minute. With the same total fluence, measurement result shows the proposed dual-layer irradiation profile can suppress post-anneal Q-factor degradation from 17% to 1%. The required active devices margin from irradiated area is also reduced by 26%.

**Abstract:**

Generative Adversarial Networks (GAN) consists of multiple deep neural networks cooperating and competing each other. Due to their complex architectures, training GANs requires huge computations and external memory accesses. However, retraining GANs with user-specific data is critical on mobile devices because the pretrained model outputs distorted images under user-specific conditions. This paper proposes an FPGAbased GAN training accelerator to enable energy-efficient domain specific optimization of GAN with user’s local data. A SELRET(Selective-Layer Retraining) is proposed to reduce the computation by 69% through selecting layers that are effective in enhancing the quality of the output. Moreover, ROLIN (Reordering Layers for Instance Normalization) is proposed to reduce the external memory accesses of intermediate data. The design is implemented on Intel’s Cyclone V, showing 51 GFLOPS peak performance with 10.04GFLOPS/W energy-efficiency for face modification of 256×256 image.

**Abstract:**

In this paper, a broad-purpose compute-inmemory solution (±CIM) able to handle arbitrary sign in both inputs/features and weights/coefficients is introduced. The ability to operate on arbitrary sign and under variable precision on both operands enables a wide range of applications, ranging from conventional neural networks to digital signal processing and monitoring. The ±CIM pipelined architecture, the reconfigurable row encoder and the adoption of a commercial 2-port bitcell allow uninterrupted memory availability for conventional read/write, even when performing in-memory computations.

**Abstract:**

Time-domain computing-in-memory (TD-CIM) architectures have three challenges for accelerating multi-bit DNNs due to their inferior bit-split convolution: poor network adaptability, massive redundant computations, and high quantization energy and error. This work firstly proposes a unique-weight kernel decomposition based convolution method for accelerating multi-bit DNNs. Then a TD-CIM based processor is designed with three techniques to address above challenges: 1) Cross-flipping based kernel decomposer to reduce memory accesses, 2) Dual-mode complementary predictor to remove redundant computations, 3) Activation-weight-adaptive pulse quantizer to reduce quantization energy and error. Fabricated in 28nm and evaluated with 1-to-8bit DNN, the processor achieves 2.4-to-152.7TOPS/W peak energy efficiency.

**Abstract:**

A 6.4 nW 1.7 % relative inaccuracy (R-IA) CMOS sub-thermal drain voltage-based temperature sensor is proposed. The proposed stabilized sub-thermal drain voltage current generator achieves a highly linear PTAT output without nonlinearity fitting or post-fabrication trimming, and increases the accuracy of the sensor. The combination of the current generator and a frequency-locked-loop relaxes the tradeoff between power and temperature stability of the current-to-frequency converter, and achieves supply-voltage-independent operation. Measured results of the prototype fabricated in a 65 nm CMOS process show that the proposed temperature sensor has a -1.0/+0.7 °C inaccuracy (= R-IA of 1.7 %) while achieving a resolution of 75 mK over a temperature range of -30 to 70 °C. The line sensitivity of the sensor is 2.8 °C/V.

**Abstract:**

A CMOS Voltage Level Detector (VLD) circuit is proposed for IoT systems which operates near the minimum energy point. It can accurately detect VCC levels of 550-640mV, making it one of the lowest voltage VLDs reported to date. A novel pull-up circuit is utilized to accurately detect fast VCC ramps of 10’s of micro seconds, which are faster than the power-up of the VLD itself. This feature enables it to operate at a low power consumption of 2.6uW. A low voltage, charge-pumped bandgap reference is utilized with a highly accurate comparator to achieve a 35mV variation across temperature and a random variation sigma of 1.68mV. This circuit is one of the lowest voltage, most highly accurate and fastest ramp-detect VLDs that have been reported in the literature.

**Abstract:**

This letter presents a low-power dynamic comparator for ultralow power applications. The prototype is designed in a 65-nm CMOS process with a supply voltage of 1 V and is compared against the widely used double tail latch comparator in terms of power consumption and input referred rms noise. The addition of cross-coupled devices to the input differential pair prevents the comparator internal nodes from fully discharging to ground in contrast to the conventional architecture. This reduces the power consumption while achieving similar noise levels. Measurements demonstrate that the proposed comparator achieves an input referred rms noise voltage of 220 µV against 210 µV for the conventional comparator with a 30% reduction in power. The proposed circuit consumes 0.19-pJ energy per comparison.

**Abstract:**

An electrochemical sensor signal acquisition chain consisting of a multichannel bidirectional current-mirror-based potentiostat and a multiplexed current-input delta–sigma ADC is presented. To enable the integration of the circuit into wirelessly powered point-of-care (PoC) diagnostics, a low-voltage and low-power implementation of the circuit is proposed. This is achieved by the use of a class-AB-amplifier based sensor front-end, which keeps the power and voltage headroom consumption at a minimum. Output stage current replication in the front-end amplifier enables bidirectional current sensing without additional measures. The proposed circuit achieves a wide dynamic range and the highest power efficiency among similar systems.

**Abstract:**

Active rectifier, biomedical implantable devices, coarsefine, delay compensation, wireless power transfer (WPT). This letter presents an active rectiﬁer with SAR-assisted coarse-ﬁne adaptive digital delay compensation technique for biomedical implantable devices. Both on- and off-delays are compensated by adjusting the comparator offset. In order to achieve accurate zero-voltage switching against process, voltage, and temperature variations, a two-step coarse-ﬁne digital tuning method is introduced. The coarse-tuning phase and the ﬁne-tuning phase are controlled by a 7-bit SAR controller and a 3-bit bidirectional counter, respectively. The proposed technique could avoid reverse current and achieve maximum conduction time for power switches. Meanwhile, it is suitable for compensating power switch with large on/off-delay variation.

**Abstract:**

A multichannel impedance-sensing CMOS chip for the readout of non-invasive light detectors in Silicon Photonics is presented. The performance of the lock-in phase-sensitive demodulator is improved thanks to a capacitive feedback transimpedance amplifier (TIA) equipped with an active discharge network, able to keep a DC output offset lower than 3 mV for leakage currents up to 4 nA while injecting a noise lower than 40 fA/sqrt(Hz). The addition of a sensor capacitance compensation system at the input of the chip allows a 30-fold increase of the stimulation amplitude, enabling the tracking of sub-picoSiemens conductance variations on a baseline of few uS, with a bandwidth of 70 Hz. The chip performance opens the way to multipoint monitoring of complex photonic systems, addressing the challenges posed by the growing complexity of these architectures.
