摘要
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 A mu m CMOS technology from TSMC with chip area 350 x 100 A mu m. The integrator consists of an adaptively biased bulk-driven linear operational transconductance amplifier (OTA) and a low-distortion common-mode feedback circuit. 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.
