ABSTRACT:
A voltage reference circuit receives an input voltage through a first port and a time varying input signal through a second port. The voltage reference circuit includes a switching circuit that is responsive to the first and the second ports and that generates an AC signal from the input voltage. The voltage reference circuit further includes a voltage multiplier circuit, coupled to the switching circuit that receives the AC signal and creates a DC signal with a selected voltage level. The voltage reference circuit further includes a voltage regulator, coupled to the voltage multiplier circuit that regulates the DC signal from the voltage multiplier circuit. A regulated output voltage is provided through an output port.
