SUCCESSIVE APPROXIMATION REGISTER ANALOG TO DIGITAL CONVERTER WITH COMPARATOR PERFORMANCE CALIBRATION

Abstract

Systems and methods are related to device (200) including but not limited to a SAR ADC. The device (200) includes a first digital to analog conversion (DAC) circuit (310) including first capacitors. The digital to analog conversion (DAC) circuit (310) is configured to adjust a first input voltage in response to a first control signal. The device (200) also includes a first comparator (330) configured to receive an adjusted input voltage from the digital to analog conversion (DAC) circuit (310). 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.
