摘要

A double-sampling pseudo-two-path bandpass ΔΣnmodulator is proposed. This modulator has an output rate equal to twicenthe clock rate, uses n/2 operational amplifiers (op-amps) for annnth-older noise transfer function, and has reduced clock feedthrough innthe signal path band. The required clocks can be simpler to implementnthan the conventional pseudo-two-path techniques. The measurednsignal-to-noise ratio and dynamic range of the fourth-orderndouble-sampling pseudo-two-path bandpass ΔΣ modulator in an30-kHz bandwidth at a center frequency of 2.5 MHz (at a clock frequencynof 5 MHz) are 62 and 68 dB, respectively
