Abstract
A method for operating a single slope analog-to-digital converter (ADC) includes providing a ramp generator to provide at least one voltage-ramp segment; applying delta-sigma modulation to the voltage-ramp generator to generate a delta-sigma modulated voltage ramp; operating a digital counter synchronously with the voltage-ramp generator; comparing the delta-sigma modulated voltage-ramp to an input voltage; and latching a count from the digital counter in response to the output of the comparator.
