A modulator (100) is provided in operative engagement with a sensor element (102) having a plurality of electrodes. The modulator (100) has a single-bit quantizer (110) electrically connected to a digital accumulator (107). The accumulator (107) accumulates output information received from the single-bit quantizer (110). The accumulator (107) converts the accumulated output information received from the single-bit quantizer (110) to a multi-bit feedback signal (108) and sends the multi-bit feedback signal (109) in a primary feedback loop (108) back to the sensor element (102). The quantizer (110) sends a single-bit feedback signal (111) in a secondary feedback loop (112) back to a point before the quantizer (110).
