Original Abstract Submitted

aspects of the present disclosure provide input-adaptive analog-to-digital conversion in which the number of conversion cycles used to convert an input signal into a digital signal is adapted based on the level (i.e., amplitude) of the input voltage. in certain aspects, the input voltage is compared with one or more threshold voltages, and the number of conversion cycles is determined based on the comparison. in certain aspects, a most significant bit (msb) capacitor in a capacitive digital-to-analog (dac) is split into two or more capacitors to provide the one or more threshold voltages.
