In this paper, a CMOS readout circuit with frequency optimization for microphone sensor arrays is newly proposed. The proposed readout circuit is attractive due to that all the analog block circuits are robust and compact to be integrated. Based upon the device parameters of 0.35 μm 2P4M CMOS technology with 3 V power supply, all the functions and(More)
An interface circuit dedicated for silicon acoustic transducer is presented. The circuit includes a transimpedance amplifier for the impedance matching between the acoustic sensor and the negative feedback amplifier along with a negative feedback amplifier with a fixed gain for pre-amplifying the acoustic signal. The input stage of the negative feedback(More)
