Abstract
An integrated circuit includes a reference voltage circuit. The reference voltage circuit includes a bipolar junction transistor (BJT) configured to receive a first current during a first phase of a clock cycle to generate a first base-emitter junction voltage, and receive a second current during a second phase of the clock cycle to generate a second base-emitter junction voltage. The reference voltage circuit includes a switched capacitor circuit configured to provide a reference voltage associated with the first base-emitter junction voltage and the second base-emitter junction voltage.
