Abstract
This work investigates the feasibility of realisation of SOI CMOS Operational Transconductance Amplifiers (OTA) operating up to 1 GHz. In contrast to a previously published microwave wideband amplifier driving low ohmic resistive line termination, OTAs for Switched-Capacitor (SC) applications need a high impedance and capacitive output node. In addition applications such as sigma-delta converters require fast OTAs. In order to reduce the settling time, the transfer function should also include a minimal amount of poles and zeros. Consequently in spite of its low voltage gain, this single-stage OTA could be of interest for high-frequency applications.
