Abstract
A circuit including a first circuit, a second circuit, and a calibration circuit. The first circuit is configured to generate a first reference voltage potential. The second circuit is configured to generate a second reference voltage potential based on a calibration signal. The calibration circuit is configured to generate the calibration signal, to adjust the second reference voltage potential, based on the first reference voltage potential and the second reference voltage potential. The calibration circuit includes a comparing circuit configured to compare the first reference voltage potential and the second reference voltage potential, and a counter configured to increment a counter value based on the comparison of the first reference voltage potential and the second reference voltage potential and generate the calibration signal based on the counter value.
