Abstract
A method and corresponding circuits for operating a parallel DMOS switch that includes a pair of P-type DMOS devices connected in series with each other and in parallel with a pair of N-type DMOS devices connected in series with each other. The method and circuits involve turning the switch on by applying gate signals to the DMOS device pairs which are generated using at least one source voltage of a DMOS device pair. The switch is turned off by setting the gate signals equal to the respective source voltages of the DMOS device pairs.
