摘要：
A 4(th)-order sigma-delta modulator is presented that offers significantly improved stability and SNR when the input is overloaded, compared to conventional single-bit modulators. The circuit combines the high linearity of a single-bit architecture with the increased stability of a multi-bit converter. Fabricated in a 0.13-mum CMOS logic process, it draws 208 muA from a 1.25V nominal supply. Clocked at 1.5 MHz, the input bandwidth is 150 Hz - 11 kHz, with SNR of 84 dB.
