A continuous-time delta-sigma modulator using feedback resistors


A third-order continuous-time delta-sigma comprised of Active-RC integrator and Gm-C integrator is presented. For the consideration of power, linearity and performance, the first integrator uses active-RC OpAmp and the others use Gm-C. To reduce the clock jitter sensitivity, we choose nonreturn-to-zero (NRZ) pulse shaping as our DAC type. For the… (More)
