A readout integrated circuit (ROIC) of infrared focal plane array (IRFPA) with low power and low noise is presented in this paper. It consists of a 384 × 288 pixel array and column-level A/D conversion circuits. The proposed system has high resolution because of the odd–even Analog to Digital Conversion (ADC) structure, containing correlated switches design, multi-Vth amplifier design and high speed high resolution comparator design including latch-stage. Designed and simulated in 0.35-μm CMOS process, this high performance ROIC achieves 81.24 dB SNR at 8.64 KS/s consuming 98 mW under 5 V voltage supply, resulting in an ENOB of 13.2-bit.

A low power readout integrated circuit (ROIC) for 512 × 512 cooled infrared focal plane array (IRFPA) is presented. A capacitive trans-impedance amplifier (CTIA) with high gain cascode amplifier and inherent correlated double sampling (CDS) configuration is employed to achieve a high performance readout interface for the IRFPA with a pixel size of 30 × 30 μm2. By optimizing column readout timing and using two operating modes in column amplifiers, the power consumption is significantly reduced. The readout chip is implemented in a standard 0.35 μm 2P4M CMOS technology. The measurement results show the proposed ROIC achieves a readout rate of 10 MHz with 70 mW power consumption under 3.3 V supply voltage from 77 K to 150 K operating temperature. And it occupies a chip area of 18.4 × 17.5 mm2.

Small-scale InGaP/GaAs heterojunction bipolar transistors (HBTs) with high-speed as well as low-current operation are demonstrated. To reduce the emitter size SE and the base-collector capacitance CBC simultaneously, the HBTs are fabricated by using WSi/Ti as the base electrode and by burying SiO 2 in the extrinsic collector region. WSi/Ti metals simplify and facilitate processing to fabricate small base electrodes, and the buried SiO 2 reduces the parasitic CBC under the base electrode. The cutoff frequency fT of 156 GHz and the maximum oscillation frequency f max of 255 GHz were obtained at a collector current Ic of 3.5 mA for the HBT with SE of 0.5 μ m ×4.5 μ m , and fT of 114 GHz and f max of 230 GHz were obtained at IC of 0.9 mA for the HBT with SE of 0.25 μ m ×1.5 μ m . A 1/8 static frequency divider operated at a maximum toggle frequency of 39.5 GHz with a power consumption per flip-flop of 190 mW. A transimpedance amplifier provides a gain of 46.5 dB·Ω with a bandwidth of 41.6 GHz at a power consumption of 150 mW. These results indicate the great potential of our HBTs for high-speed. low power integrated circuit applications.

In the recent years the advancement in the field of microelectronics integrated circuit (IC) design technologies proved to be a boon for design and development of various advanced systems in-terms of its reduction in form factor, low power, high speed and with increased capacity to incorporate more designs. These systems provide phenomenal advantage for armoured fighting vehicle (AFV) design to develop miniaturised low power, high performance sub-systems. One such emerging high-end technology to be used to develop systems with high capabilities for AFVs is discussed in this paper. Three dimensional IC design is one of the emerging field used to develop high density heterogeneous systems in a reduced form factor. A novel grouping based partitioning and merge based placement (GPMP) methodology for 3D ICs to reduce through silicon vias (TSVs) count and placement time is proposed. Unlike state-of-the-art techniques, the proposed methodology does not suffer from initial overlap of cells during intra-layer placement which reduces the placement time. Connectivity based grouping and partitioning ensures less number of TSVs and merge based placement further reduces intra layer wire-length. The proposed GPMP methodology has been extensively against the IBMPLACE database and performance has been compared with the latest techniques resulting in 12 per cent improvement in wire-length, 13 per cent reduction in TSV and 1.1x improvement in placement time.

This paper presents a low power CMOS analog integrated circuit of a Takagi–Sugeno fuzzy logic controller with voltage/voltage interface, small chip area, relatively high accuracy and medium speed, which is composed of several improved functional blocks. Z-shaped, Gaussian and S-shaped membership function circuits with compact structures are designed, performing well with low power, high speed and small areas. A current minimization circuit is provided with high accuracy and high speed. A follower-aggregation defuzzification block composed of several multipliers for center of gravity (COG) defuzzification is presented without using a division circuit. Based on these blocks, a two-input one-output singleton fuzzy controller with nine rules is designed under a CMOS 0.6 μm standard technology provided by CSMC. HSPICE simulation results show that this controller reaches an accuracy of ±3% with power consumption of only 3.5 mW (at ±2.5 V). The speed of this controller goes up to 0.625M Fuzzy Logic Inference per Second (FLIPS), which is fast enough for real-time control.
