Abstract
A voltage regulator circuit includes a digital control block, an amplifier and a transistor. The digital control block receives a first reference voltage and a feedback voltage, converts the received voltages from analog to digital signals, performs an integration operation on the converted signals, and converts the result of the integration operation to an analog signal. The amplifier is responsive to the output of the digital control block and to a regulated output voltage of the regulator circuit. The transistor has a first terminal responsive to the output of the amplifier, a second terminal that receives the input voltage being regulated, and a third terminal that supplies the regulated output voltage. The transistor may be an NMOS or a bipolar NPN transistor. The feedback voltage may be generated by dividing the regulated output voltage. The digital control block optionally generates a biasing signal to bias the amplifier.
