Abstract: A voltage regulator configured to receive a supply voltage from a voltage supply and provide a regulated voltage to digital circuitry is provided. The voltage regulator comprises first circuitry configured to inhibit high frequency energy generated by the digital circuitry from transmitting into the voltage supply, second circuitry configured to inhibit low frequency energy generated by the digital circuitry from transmitting into the voltage supply, and third circuitry configured to maintain the regulated voltage at a substantially constant value in response to a current drawn by the digital circuitry.

Abstract: An oscillator includes a plurality of varactor cells to receive a control signal to control a frequency of the oscillator. Each of the varactor cells includes a switch that includes a first terminal to receive the control signal and a second terminal such that the switch operates to control a capacitance of the varactor cell in response to a voltage between the first and second terminals. The oscillator includes a bias circuit to provide a different bias voltage to each second terminal and an amplifier that is coupled to the varactor cells to generate an oscillating signal.
