We have been developing low power cryogenic readout electronics for space borne large format far-infrared image sensors. As the circuit elements, a fully-depleted-silicon-on-insulator (FD-SOI) CMOS process was adopted because they keep good static performance even at 4.2 K where where various anomalous behaviors are seen for other types of CMOS transistors. We have designed and fabricated sever...

This paper presents an improved linearity variable-gain amplifier (VGA) in 0.18-µm CMOS technology. The lineari­ty improvement is resulted from employing a new combinational technique, which utilizes third-order-intermodulation (IM3) cancellation mechanism using second-order-intermodul­ation (­IM2) injection, and intermodulation distortion (IMD) sinking techniques. The proposed VGA gain cell co...

The tradition of implementing analogue circuits by means of voltage amplifiers is almost as old as the concept of electronic circuit design. The integrated electronic circuit, however, is a relatively new concept. Furthermore, integrated electronic circuits have significantly different limitations and strengths to the conventional discrete electronic circuits have. Since the active devices in i...
