Abstract

Key Words: totem pole, cross-conduction current, On-resistance (RDSON) It is often necessary to switch a field-effect transistor (FET) at high speeds with a driver circuit. It is common for such driver circuits to have a totem-pole output, which includes a "source" transistor for sourcing current to the gate of the FET and a "sink" transistor for removing charge from the gate of the FET. The source and sink transistors may respectively be considered to be part of active pull-up and pull-down circuits.
