A second-order integrated LC bandpass delta-sigma modulator is presented. This modulator is implemented in a 0.5-μm bipolar process and can be used for digitizing radio frequency or high intermediate frequency signals. It employs an integrated LC resonator with active Q-enhancement and two nonreturn-to-zero digital-to-analog pulse-shaping feedback loops. The modulator test chip achieves a signal-to-noise ratio of 57 dB over a 200-kHz bandwidth for converting a 950-MHz signal, and dissipates 135 mW with a 5-V supply
