Classification: CPC H | IPC G  H

Claim 0:
1. A switch comprising:
a first port;
a second port;
a third port;
a first switch circuit configured to selectively couple a signal received at the first port to the second port based on a first switch control signal; and
a second switch circuit configured to selectively couple the signal received at the first port to the third port based on a second switch control signal, wherein the second switch circuit comprises an accumulated charge sink (ACS) and a transistor comprising a source, a drain, a gate, and a body coupled to the ACS, and wherein the ACS is configured to receive a bias voltage during at least a portion of a duration when the second switch circuit is configured to not couple the signal received at the first port to the third port to prevent charge from accumulating in the body,
wherein the switch is configured to:
pass the signal received at the first port to the second port via the first switch circuit when the first switch circuit is in an on state and the second switch circuit is in an off state; and
pass the signal received at the first port to the third port via the second switch circuit when the first switch circuit is in an off state and the second switch circuit is in an on state.
