Abstract

This paper proposes power-efficient ICs for measuring the signal of a Floating Gate (FG) radiation sensor. It implements the function of converting the current signal generated in the FG into a digital signal through a regulated-cascode current reference (RCCS) and a time-based quantizer. The proposed sensor interface ICs are implemented with the PDK of DB Hitek process, securing a 45 dB SNR with only 14.7 uW power consumption.
