Abstract
According to one embodiment, a radio frequency (RF) transceiver includes a local oscillator generator (LOGEN) circuit configured to receive an adaptive supply voltage. The LOGEN circuit is coupled to a variable power supply for providing the adaptive supply voltage. A process monitor for the LOGEN circuit is in communication with the variable power supply through a power supply programming module. As a result, the adaptive supply voltage can be adjusted according to data supplied by the process monitor. A method for adaptively powering a LOGEN circuit comprises providing power to an RF device, monitoring a process corner of said LOGEN circuit, determining a supply voltage corresponding to the process corner, and adjusting the supply voltage to adaptively power the LOGEN circuit.
