Abstract
The present disclosure relates to voltage regulation techniques. In some embodiments, a voltage regulator is configured to regulate an output voltage based on a reference voltage. The voltage regulator comprises an analog-to-digital converter, an encoder, a decoder and a power stage. The analog-to-digital converter receives the reference voltage and an output voltage of the voltage regulator and provides a digital error signal. The encoder is coupled to the analog-to-digital converter output and configured to provide a multi-bit digital control signal based upon a present value of the digital error signal, a plurality of pre-determined coefficients, and a plurality of previous values of the digital error signal. The decoder is coupled to the encoder and configured to generate a plurality of control signals based on the multi-bit digital control signal. The power stage comprises a plurality of power cells which are coupled to a power supply and which receive the plurality of control signals, respectively.
