CMOS preamplifier for electret microphones Conference Paper

abstract

• In this paper a CMOS preamplifier for capacitive sources is presented. The 20 dB gain preamplifier achieves a dynamic range of 54 dB while the total harmonic distortion is below to -50 dB. Monte Carlo analyses have shown output random offset voltages below to 40 mvolts. The power consumption of the proposed preamplifier is 24 watts. All this has been achieved due to the use of a novel resistor and linearized OTAs.
