Abstract
Delta-sigma modulation utilizing continuous-time input and discrete-time loop filter. An apparatus includes an input circuit, a switched-capacitor, an integrator, a quantizer and a feedback loop. The input circuit receives an analog signal and produce an analog input signal, the input circuit comprising a resistor-capacitor (RC) integrator. The switched-capacitor samples the analog input signal and produce a discrete-time, sampled input signal. The integrator processes the discrete-time, sampled input signal. The quantizer converts an output of the integrator to a digital signal. The feedback loop provides the digital signal to respective inputs of the RC integrator and the integrator.
