Abstract
A circuit comprises a programmable voltage regulator and an oscillator. The programmable regulator generates a regulated supply voltage using an input voltage and changes the regulated supply voltage from a first voltage to a second voltage in response to a first control signal. The first and the second voltages are generated using charge from the input voltage. The regulated supply voltage drives the oscillator. The oscillator varies a frequency of a periodic output signal within a frequency range in response to changes in a control voltage. The frequency range of the periodic output signal varies when the first control signal causes the regulated supply voltage to change from the first voltage to the second voltage.
