Abstract

A sampled band-gap voltage reference circuit which has quicker regeneration of the voltage reference signal after degeneration of the voltage reference signal due to additional loading. The voltage reference circuit prevents interference from the circuit source inputs to the operational amplifier by selective switching. The selective switching of the circuit allows the operational amplifier to regenerate the output voltage up to ten times quicker than prior art devices of the same size.
