Abstract :
This paper describes a VLSI automatic quality control pitch detector circuit which can be used for detecting the identity of a unique bird. The detector is based on a previous VLSI model of the local gain control mechanism of the outer hair cells of the biological cochlea. This work presents characterization results from a 20-channel chip fabricated in a 4-metal 2-poly CMOS 0.35 μm technology with estimated dynamic range of 70 dB, power consumption of 825 nW per channel, frequency range covering 0.4-10 kHz and mean Q of 6.31. Results are shown for a pitch detection experiment with a tuned resonator.
