Abstract
A reference signal generator includes a voltage reference, an amplifier coupled to the voltage reference, and a precharge circuit coupled to the amplifier. The voltage reference is configured to generate a constant voltage. The amplifier is configured to receive the constant voltage from the voltage reference and generate a regulating primary output signal and a non-regulating secondary output signal. The precharge circuit is configured to charge a noise reduction capacitor with the non-regulating secondary output signal.
