ABSTRACT:
Disclosed herein is a reference voltage generator circuit for providing and regulating a reference voltage. In one embodiment, the generator circuit includes a first subcircuit configured to provide a bias current based on a supply voltage, where the bias current varies based on at least one performance characteristic of components comprised in the first subcircuit. The circuit also includes a second subcircuit coupled to the first subcircuit and the supply voltage. In this embodiment, the second subcircuit includes first components configured to generate a bias voltage based on and proportional to the bias current, and second components having the at least one performance characteristic. In addition, the second components in such an embodiment are configured to generate a compensation voltage based on the bias voltage that varies inversely to variations in the bias voltage to compensate for the variations in the bias voltage. Furthermore, the second circuit is further configured to generate the reference voltage based on the bias voltage and the compensation voltage. Also disclosed is a method of manufacturing a reference voltage generator circuit for providing and regulating a reference voltage.
