Abstract
A modulator is provided in operative engagement with a sensor element having a plurality of electrodes. The modulator has a single-bit quantizer electrically connected to a digital accumulator. The accumulator accumulates output information received from the single-bit quantizer. The accumulator converts the accumulated output information received from the single-bit quantizer to a multi-bit feedback signal and sends the multi-bit feedback signal in a primary feedback loop back to the sensor element. The quantizer sends a single-bit feedback signal in a secondary feedback loop back to a point before the quantizer.
