Abstract
A first-order sigma-delta analog-to-digital converter includes an input terminal, an integrator circuit, a comparator, and control circuitry. The input terminal is configured to receive a unipolar input signal to be digitized. The integrator circuit is coupled to the input terminal. The comparator is coupled to an output of the integrator circuit. The control circuitry is coupled to the integrator circuit and the comparator. The control circuitry is configured to equalize time that an output signal generated by the integrator circuit is greater than zero and time that the output signal generated by the integrator circuit is less than zero during digitization of the unipolar input signal.
