摘要

This paper presents a resistor-based high-resolution temperature-to-digital converter with an energy-efficient incremental delta-sigma analog-to-digital converter (IADC), implemented by hybrid continuous-time and discrete-time circuits. To reduce the flicker noise, the chopper switches are incorporated in the 1st -integrator. To further mitigate the degradation caused by the chopper, a finite impulse response (FIR) digital-to-analog converters (DAC) is added in the feedback loop filter to create frequency notches and eliminate the aliasing of the out-of-band noise due to chopping frequency. The proposed circuit is implemented in 180-nm CMOS process and, and the overall circuit consumes 166μ W from a 1.8 V power supply. The measured temperature resolution is less than 7.7 m°C(1σ) in 0.1 ms, which corresponds to a resolution figure of merit (FoM) of 0.984
