A third-order complementary metal-oxide-semiconductor sigma-delta modulator operating between 4.2 K and 300 K.

This paper presents a third-order switched-capacitor sigma-delta modulator implemented in a standard 0.35-μm CMOS process. It operates from 300 K down to 4.

A cryogenic analog to digital converter operating from 300 K down to 4.4 K.

This paper presents a cryogenic successive approximation register (SAR) based analog to digital converter (ADC) implemented in a standard 0.35 microm complementary metal oxide semiconductor (CMOS) process. It operates from room temperature down to 4.
