Abstract
A device and method for analog to digital conversion is disclosed. The device can have a first amplifier operable to receive an input voltage and output a first control signal. The device can also have a first voltage-controlled oscillator (VCO) operably coupled to the first amplifier and configured to output a first signal based on the first control signal, the first signal having a sensor frequency. The device can also have a first switched-capacitor resistor operably coupled to the first VCO and to the first amplifier, the first switched-capacitor resistor configured to receive and be controlled by the sensor frequency. The device can also have a sensor counter operably coupled to the first VCO and configured produce a sensor count based on the sensor frequency. The device can also have a register configured provide a digital output proportional to the input voltage based on the sensor count.
