Reconfigurable analog-to-digital converter

An integrated circuit (IC) includes an analog to digital converter (ADC) circuit having an ADC input and an ADC output. The ADC circuit is configured to receive an input signal at the ADC input and generate a digital output signal at the ADC output based on the input signal. An ADC circuit path is coupled between the ADC input and the ADC output. The ADC circuit comprises a plurality of capacitors coupled between reference voltage sources and the ADC circuit path. The ADC has a reconfigurable resolution and a reconfigurable sampling rate. The ADC circuit is configured to scale the reference voltage sources and/or the plurality of capacitors based on the reconfigurable resolution.
