A new topology of piezoresistive pressure sensor signal conditioner based on the alternative current loop is proposed. The mathematical model of this sensor is discussed and its advantages are revealed. The optimal procedure for model parameter estimation based on the maximum likelihood method is derived. The results of computer simulation confirming the theoretical result are given.
