Abstract :
Two second-order bandpass delta-sigma A/D modulators have been implemented in a 0.8 μm BiCMOS process to demonstrate the feasibility of converting a 10.7 MHz radio IF signal to digital form. The circuits, based on switched-C biquads, are clocked at 42.8 MHz and demonstrated 55 dB SNR in a 200 KHz bandwidth while dissipating 60 mW of power from a 5 V supply
