CMOS Automatic Gain Control for Hearing aid devices Conference Paper uri icon

abstract

  • In this paper a CMOS Automatic Gain Control (AGC) for Hearing aid devices is proposed. Montecarlo analyses have shown total harmonic distortions below 0.5% and 0.6% for uncompressed and hard compressed operations, respectively. Dynamic Range is 69 dB while the THD is around 0.5%. Power consumption for the complete AGC is 54 μWatts under normal conditions and 162 μWatts for maximum compression operation. Attack and release times are below than 5 ms. The AGC is operated with ±1.5 supply voltages.
