Abstract
A switchable charge pump (SCP) combines a switching element and a charge pump. An SCP can be utilized within an RF circuit to allow the charge pump to be activated or deactivated in the circuit depending on incident RF power level. Multiple SCPs can be utilized to provide a generalized a single-pole N-throw (SPNT) system architecture. In one example, an RF transmit-receive (T/R) system utilizes SCPs to operate in one of three modes: transmit mode, receive mode, or self-selecting terminate mode.
