Abstract
A frequency synthesizer device provides amplitude control. Using switch circuit operating in a first mode, a charge voltage is applied to an oscillator circuit that an inductive-capacitive (LC) tank circuit. The LC tank circuit has a capacitive element, and an inductive element that is connected to the capacitive element. Using the switch circuit operating in a second mode, the LC tank circuit is enabled to oscillate. Using driver circuits that are response to a voltage applied to the tank circuit, current is reinforced in the LC tank, and the reinforcement is based upon a transconductance gain of the driver circuits. Using a calibration circuit, an amplitude of an output signal from the oscillator circuit is detected. In response to the detected amplitude, the transconductance gain is adjusted by enabling or disabling auxiliary circuits from plurality of auxiliary circuits.
