Originální abstrakt

A new solution for an ultra-low-voltage bulk-driven asynchronous delta sigma modulator (ADSM) is described in the paper. While implemented in a standard 0.18 um CMOS process from TSMC and supplied with VDD = 0.3 V, the circuit offers a 53.3 dB signal to noise and distortion ratio (SNDR), which corresponds to 8.56-bit resolution. Besides, the total power consumption is 37 nW, the signal bandwidth is 62 Hz and the resulting power efficiency is 0.79 pJ/conversion. The above features have been achieved employing a highly linear operational transconductance amplifier (OTA) and a hysteretic comparator based on non-tailed differential pair.
