Systems and methods for improving output resolution of an optical drive circuit in an optical sensor. The optical sensor circuit includes an optics circuit that generates analog measurement data, a detector circuit that detects the analog measurement data and converts the analog measurement data to a digital measurement data, and a signal processing circuit that demodulates the digital measurement data and generates a segmented digital signal based on the demodulated digital measurement data. The optical sensor circuit further includes an optics drive circuit that generates an analog drive signal based on the segmented digital signal. The analog drive signal is then used to drive the optical circuit.
