dc.description.abstract | In this paper, an analog correlator based analog front end with gain control circuit for hearing aid devices is designed and fabricated with 0.18 mu m CMOS process. The proposed analog front end consists of an analog correlator comprised of a multiplier, an integrator, and a mixed mode variable gain amplifier. The analog correlator is utilized to ensure the low input referred noise. A gain control circuit is implemented in variable gain amplifier. Based on the output of piezoelectric micro-phone, designed gain control circuit automatically sets the gain. The investigated analog front end offers lower noise and wider dynamic range with compact size compared to conventional architecture. It achieves a 42 nV(rms) input referred noise and 84 dB signal to noise ratio. The total area of the designed analog front end circuit is 386 mu m x 569 mu m. Designed circuit is interfaced with a sensor model of piezoelectric microphone and its performance is successfully verified against simulation results. | - |
