Abstract
A VCO supply voltage regulator includes a control voltage input, first and second supply voltage inputs, a regulated voltage output, a current source and an amplifier. The current source is coupled between the first voltage supply input and the regulated voltage output and has a bias input. The amplifier has an amplifier input coupled to the control voltage input, an amplifier output coupled to the bias input and a feedback input coupled to the regulated voltage output.
