Claim Text:
1. A device for analog to digital conversion comprising: a first amplifier operable to receive an input voltage and output a first control signal; 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; 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 of the first signal; a sensor counter operably coupled to the first VCO and configured produce a sensor count based on the sensor frequency of the first signal; and a register configured provide a digital output based on the sensor count.
