Abstract
An operational transconductance amplifier (OTA) is typically used in the optical transmitter for an analog control. Additionally, for an OTA, the input range may be shifted to the output range and the output range is to be limited to safely operate a cascode/drive transistor. OTA operation is linear and is not digitally switched. Presented herein is an OTA design that can operate with a power supply voltage greater than the drain-source voltage (VDS) breakdown voltage. The output range can be limited to the gate-source voltage (VGS) breakdown range and can be adapted to a desired range using a cascode transistor. Additionally, the OTA design presented herein can operate safely in non-switched applications.
