摘要
A voltage reference circuit receives an input voltage at a first port and a time varying input signal at a second port. The voltage reference circuit includes a switching circuit that is responsive to the first and 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 to receive the AC signal and to create a DC signal with a selected voltage level. The voltage reference circuit further includes a plurality of voltage reference modules, coupled together to form a voltage reference stack, and coupled to the voltage multiplier circuit to receive the selected voltage level and output a precise reference voltage.
