Original Abstract

This short paper presents the experimental results for a 0.3-V fully-differential OTA-C integrator, implemented in a standard n-well 0.18 µm CMOS technology from TSMC with chip area 350 µm x 100 µm. The integrator consists of an adaptively biased bulk-driven (BD) linear operational transconductance amplifier (OTA) and a low-distortion common-mode feedback circuit (CMFB). The integrator can operate with supply voltages ranging from 0.3 to 0.5 V. For a 0.3-V version its cutoff frequency can be tuned from 50 to 334 Hz for a 220 pF load capacitance. For a nominal biasing current its power consumption is 50 nW and the dynamic range is 75 dB.
