dc.description.abstract | A 1-bit sigma-delta modulator (SDM) with an on-chip preamplifier for digital electret microphones has been implemented. A differential gm-opamp-RC preamplifier eliminates the traditional single-ended JFET interface and is integrated with an on-chip SDM by removing all external components. The proposed time-domain noise isolation technique preserves circuit performance under a single power supply condition. The prototype implemented in a 0.18 mu m CMOS technology achieves a 78 dB dynamic range and 62 dB peak signal-to-noise + distortion ratio (both A-weighted) with a current consumption of 450 mu A under a 1.8 V supply. | - |
