Abstract
This chapter describes operational transconductance amplifiers (OTAs) and their linearization for use in g m -C filters. Super-source-follower and digitally programmable OTAs are detailed. The common-mode feedback used in these OTAs and a buffer amplifier are described. A OTA implemented in 120 nm CMOS is introduced inclusive measured results.
