Abstract

A 1.5 V stereo audio CODEC in 0.13 μm CMOS demonstrates circuit techniques that minimize power consumption for microphone and speaker interfaces. The CODEC includes a 0.35 mA microphone PGA, a 0.35 mA continuous-time ΔΣ ADC and a 1 mA Class-AB speaker amplifier. The audio input and output paths achieve 92 dB and 98 dB SNR, respectively, with 6.5 mA total stereo current.
