Abstract
A reference voltage generator is disclosed. The reference voltage generator may include an operational transconductance amplifier (OTA), a bias generator, a first flipped voltage follower, a bias filter, a control signal filter, and a second flipped voltage follower. The OTA and the first flipped voltage follower may generate a control signal based on a reference voltage and a bias voltage from the bias generator. The bias filter may filter the bias voltage and the control signal filter may filter the control signal. The second flipped voltage follower may generate the output voltage based on the filtered bias voltage and the filtered control signal.
