Systems and methods are provided for converting analog data to digital data that can include a discharge capacitor coupled to a voltage source. The voltage source supplies an initial data charge to the discharge capacitor; an amplifier coupled to the discharge capacitor; a divider circuit coupled to the amplifier; and a comparator coupled to the amplifier and the divider circuit. The divider circuit includes a first capacitor, a second capacitor, and a switch that is operated to alternately divide a remaining charge Q by 2N using the first and second capacitors until the remaining data charge Qin at the amplifier is below a threshold value in the process of converting analog data to digital data.
