A baseband continuous-time multi-bit /spl Sigma//spl Delta/ modulator achieves 88dB dynamic range over a 1.1MHz signal bandwidth consuming 62mW from a 3.3V supply. Excess loop delay encountered in conventional continuous-time modulators is eliminated by the proposed architecture. Clock-jitter sensitivity is considerably reduced compared with prior designs.
