In this paper, the radiation response of 90 nm bulk Si MOS devices irradiated by heavy ions is experimentally studied. Due to the intrinsic random incident of heavy ions, different performance degradation is observed, such as threshold voltage shift, saturation current change and maximum transconductance degradation. These performance degradations may be attributed to the displacement damage in channel region, interface states at gate oxide interface and trapped charges in STI, which are generated by heavy ion irradiation. Furthermore, the statistical analysis on the performance degradation of 90 nm bulk Si MOS devices is also demonstrated *** results indicate that the performance variation of90 nm bulk Si MOS devices enlarges after heavy ion irradiation compared with un-irradiated ***, the standard variation of threshold voltage shift, DIBL shift and off-state leakage current degradation induced by heavy ion irradiation increases with the decrease of gate width, which should be paid more attention. The results may provide guideline for radiation-hardened design.

The 2-D limited regrowth of α-Si is proposed to achieve larger grain size and smoother surface simultaneously with conventional rapid thermal annealing process. Transmission line method is carried at room temperature and 100 K temperature separately to confirm that the boundary scattering and ionization scattering are possibly suppressed by the capping layer method due to less grain boundary and trapped ionization centers.

In this paper, nanoscale germanium(Ge) fin etching with inductively coupled plasma(ICP) equipment by Cl/BCl/Ar gas is experimentally demonstrated. The impact of Cl/BCl/Ar gas ratio on etching induced Ge surface roughness, etch rate, sidewall steepness, uniformity and layout dependence are comprehensively investigated. The surface roughness is improved by increasing Ar flow rate. A nearly vertical Ge Fin is obtained by optimizing Cl/BCl/Ar gas ratio. By using silicon oxide as hard mask, 60nm-width Ge Fin array with height of 100 nm is experimentally illustrated with high uniformity of etch depth and Fin width. Therefore, this method shows great potential for Ge-based multi-gate device fabrication.

A novel self-turnoff control circuit for program process of one-time programmable(OTP) cell is proposed. Utilizing the current turnoff technology after the breakdown of OTP cell, it lowers the power consumption efficiently compared with traditional structures without turnoff mechanism. In addition, an additional delay circuit is also attached to the self-turnoff circuit to ensure the complete breakdown of OTP cell. The simulation results show that the average power consumption of proposed circuit decreases to about 3nA in the whole program process.

A buck DC-DC converter with very high light load efficiency is presented in this paper. It introduces hysteretic control when the large output ripple problem is not critical, especially in light-load condition. Moreover, a fast-response zero current detector(ZCD) is adopted to make the converter work in discontinuous conduction mode(DCM). Due to hysteretic control extremely simplified the control circuits, the converter is divided into two independent loops, which further simplifies the optimization of power consumption. The proposed converter is fabricated in a standard 55 nm CMOS process. It converts 1.8-2.5 V battery voltage into a stable output voltage of 1 V, and offers 100μA to 10 mA light-load current output. The hysteretic converter achieves peak efficiency of 88.5% and 90%, with a supply voltage of 2.5 V and 1.8 V, respectively.

This paper presents a novel fractional-N digital PLL structure with a digitally controlled phase interpolator(DPI) and a time-to-digital converter(TDC). In this structure, a short bit-width DPI and a short bit-width TDC are combined to achieve high phase resolution and low in-band phase noise. Moreover, since the DPI readily achieves 360° phase range and the TDC provides good linearity, no extra complex calibration is needed, which simplifies the design and saves power and chip area. Designed in a 55-nm CMOS technology, the proposed digital PLL achieves-103 d Bc/Hz in-band phase noise at 2.4 GHz output frequency. It consumes 2.4 mW from a 1.2-V supply and occupies 0.18 mm2 active chip area.

This paper presents a 7.9 fJ /conversion-step 10-bit 125 MS/s successive approximation register(SAR) analog-to-digital converter(ADC) on the basis of a monotonic capacitor switching procedure. Simplified power-efficient digital control logic, multi-layer sandwich capacitor structure and high-speed level-shift bootstrapped sampling-and-holding(S/H) blocks are employed to achieve high performance with low power consumption. The prototype is implemented in 55 nm standard CMOS process, occupying an active area of 0.18 mm × 0.20 mm. Post simulation results show that an SNDR of 54.01 d B and an ENOB of 8.7 bit can be achieved by consuming 0.41 mW of the ADC core from a 1.2 V supply, and a figure of merit(FOM) of 7.9 fJ /conversion-step.

Stochastic computing (SC) is a promising alternative to conventional deterministic computing, which enables ultralow power, high error-tolerance and massive parallelism, but not requiring new devices. In this paper, the feasibility of SC circuits based on state-of-the-art FinFET technology are investigated for the first time, with on-chip image processing application as an example. Practical technical issues are carefully examined, including static and transient device variations in 16/14nm FinFET. SC design optimization procedure is also proposed, which can considerably decrease its energy consumption without the penalty of accuracy. The results provide helpful guidelines for energy-efficient stochastic circuit design in new-paradigm computing.
