Abstract

Systems and methods are related to device including but not limited to a SAR ADC. The device includes a first digital to analog conversion (DAC) circuit including first capacitors. The digital to analog conversion (DAC) circuit is configured to adjust a first input voltage in response to a first control signal. The device also includes a first comparator configured to receive an adjusted input voltage from the digital to analog conversion (DAC) circuit. The first control signal is provided in response to a target input voltage and a sensed input voltage and adjusts the first input voltage using the first capacitors.
