Abstract
A digital voltmeter, where a number of clock pulses for a first ramp voltage to reach an input voltage is determined. Next, a number of clock pulses for a second ramp voltage to reach the input voltage is determined. One of the first and the second ramp voltages having a least number of clock pulses to reach the input voltage is determined. A determination is made for a number of clock pulses for the determined one of the first and the second ramp voltages to reach a reference voltage. A digital code is generated for the input voltage based on the determined number of clock pulses for reaching the reference voltage and the determined least number of clock pulses for reaching the input voltage.
