  • Abstract
    This paper presents an electronic attenuator for audiometric applications, including an on-chip power amplifier which drives 8 Vppon a 7Ω resistive load. The 24 mm2chip, fabricated in a 2 µm high-voltage CMOS process, achieves 147 dB of dynamic range and 80 dB of signal-to-noise ratio, consuming 33 mA from a ±5 V power supply.
