Abstract:
A system includes a voltage controlled oscillator (VCO) having an adjustable amplitude. The amplitude of the VCO may be adjusted by adjusting voltage level present at a center tap node of an inductor. The VCO may have an adjustable amplitude that may be programmed on a chip-by-chip basis based on a chip parameter, power consumption, or oscillator performance.
