System and method for increasing the frequency tuning range of a
RF/microwave LC oscillator. An electronic communications device includes
a controller to regulate the operation of the electronic communications
device, a modem coupled to the controller, a radio frequency unit coupled
to the controller and to the modem, an oscillator coupled to the
controller and to the radio frequency unit, and an amplifier coupled to
the radio frequency unit. The oscillator produces a timing and reference
signal for the radio frequency unit based on control information from the
controller. The oscillator includes a multi-tap inductor that may
controllably alter its effective inductance to change the timing and
reference signal provided to the radio frequency unit.
