METHOD FOR USING A SENSOR SYSTEM HAVING A SINGLE-BIT QUANTIZER AND A MULTI-BIT FEEDBACK LOOP |
摘要 |
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. |
