DIFFERENTIAL SIGNAL CONDITIONER WITH COMMON MODE VOLTAGE ERROR COMPENSATION
Abstract(summary):
A differential signal conditioner circuit with common mode voltage (CMV) compensation is provided. The circuit includes a signal multiplexer (308) that receives a input signal that includes a high and low signal and a reference CMV signal, a differential amplifier (302) coupled to the signal multiplexer (308) that receives the reference CMV signal and outputs a CMV error value during a first cycle, and receives the input signal and outputs an amplified difference signal during a second cycle. The circuit also includes a CMV measurement circuit (315) that receives the reference CMV signal and outputs a confirmation value during the first cycle, and receives the input signal and outputs a CMV compensation value during the second cycle, and a processing element (309) that receives the CMV error value, the amplified difference signal, the CMV compensation value, and a differential amplifier gain value and generates a CMV compensated output based on the received signals and values.
