Abstract
A bi-directional switch circuit includes a pair of N-type MOS devices connected in series with a common source terminal, and a pair of P-type MOS devices connected in series with a common source terminal. The series connected N-type devices are connected in parallel with the series connected P-type devices in a configuration that includes a first input/output (I/O) point of the switch circuit being connected to a drain of a first one of the N-type devices and a drain of a first one of the P-type devices. The parallel configuration also includes a second I/O point of the switch circuit being connected to a drain of a second one of the N-type devices and a drain of a second one of the P-type devices.
