Abstract :
A third-order continuous-time delta-sigma modulator achieving 76dB dynamic range over 5MHz signal bandwidth is presented. The modulator has a monotonic lowpass signal transfer function and achieves over 70dB anti-aliasing. The prototype chip implemented in a 130nm CMOS process consumes 6mw power from a single 1.2V supply and occupies 0.56 mm2 active area.
