Abstract
An inverter based on a compound semiconductor uses a depletion mode transistor as the pull-up device, and a current source to bias the pull-up device. The current source is electrically coupled to a source terminal of the pull-up device. As a result, the current source continues to conduct current through the pull-up device, whether the inverter output is high or low, to ensure rapid response of the inverter.
