Abstract

Acoustic and sonar analog signal processing applications require design of operational transconductance amplifiers (OTAs) that can be configured over wide frequency range in multiple bands and yet achieve low power consumption and low harmonic distortion. A fully differential, linear OTA is presented with digitally programmable transconductance ranging over three decades of dynamic range. Measurements from a prototype fabricated in a 0.5μm CMOS process demonstrate a 0.4 nA/V to 0.8 μA/V transconductance range, 40 dB common-mode rejection ratio (CMRR), and -48 dB third-order harmonic distortion, at 12 μW power dissipation.
