    Abstract: Low noise voltage generation circuitry includes a voltage source, a low-pass filter with one or more filter stages, and an amplifier selectively coupled to the filter stages. Each filter stage includes a resistor and a pair of capacitors of equal capacitance. The amplifier has an input selectively coupled to an output port of the voltage generation circuitry and has an output selectively coupled to the pair of capacitors in each filter stage. During a sensing phase, the amplifier senses the voltage at the output port. During a first charging phase, the amplifier has a first polarity and charges one of the pair of capacitors in each filter stage. During a second charging phase, the amplifier has a second polarity and charges another one of the pair of capacitors in each filter stage. During a final phase, the pair of capacitors within each filter stage are shorted together to cancel out an amplifier offset while the output port instantaneously settles to the target voltage.
