ABSTRACT:
Crowbar current in a CMOS amplifier circuit is limited during a transition state where one transistor is being turned on and another transistor is being turned off. The transistor that is being turned off is caused to pass through a midpoint state before the transistor that is being turned on is allowed to transition through a similar midpoint state. In one embodiment, independent gate voltages are applied to the P and N transistors of a CMOS amplifier. The gate voltages are independently controlled prior to passage through a midpoint level and then converge towards one another after passage through the midpoint state.
