Abstract
A circuit includes a P-channel transistor formed in a P-well and an N-channel transistor formed in an N-well. The first P-channel transistor has a control electrode connected to the P-well. The N-channel transistor is coupled in series with the P-channel transistor and has a control electrode connected to the N-well. Connecting the control electrodes of the P-channel and N-channel transistors to respective P-well and N-well effectively reduces crowbar current in the circuit.
