Abstract
An apparatus and method for providing a stable gain over wide frequency range in a VCO are presented. A VCO uses a waveform generator along with a bias generator having a frequency select input. The frequency select input is used to adjust the amount of output current and/or gain of the bias generator. The output current of the bias generator determines the frequency of the output of the waveform generator. Multiple bias and waveform generators may be used to expand the frequency range of the VCO. A PLL may be programmed for a variety of output frequencies by using the frequency select input of the VCO.
