A low-power continuous-time ΔΣ modulator for Electret microphone applications

A continuous-time delta-sigma modulator that maybe used as an interface for Electret microphones is presented. The third order modulator comprises a single-ended-to-differential-converter integrated inside the loop-filter with a single-ended high-impedance input, an RC integrator on the first stage...
