1. A sensor device, comprising:
a multiplexer stage configured to sequentially select sensor outputs from one or more sensors continuously, resulting in a stream of selected sensor outputs;
a charge-to-voltage converter operatively coupled to the multiplexer stage and configured to convert a charge from a first sensor of the one or more sensors to a voltage;
a single resettable integrator operatively coupled to the charge-to-voltage converter and configured to demodulate and integrate the voltage, resulting in an integrated voltage; and
analog-to-digital converter operatively coupled to the single resettable integrator and configured to digitize the integrated voltage to a digital code.
