This paper introduces the concept of frequency-translating, bandpass delta-sigma modulator in continuous-time. The system level design and simulation results of the delta-sigma modulator are presented. The DAC jitter performance of the continuous-time, frequency translating bandpass delta-sigma modulator is presented. The DAC jitter performance of the frequency translating modulator and conventional lowpass delta-sigma modulator are compared.
