Abstract:
This paper presents a continuous-time quadrature bandpass ΔΣ ADC that achieves 60dB DR and 67.4dB SFDR at 1MHz BW and 1MHz IF. The modulator uses capacitive feedforward architecture for the 3rd order loop filter for reduced power consumption and a local feedback loop for optimized noise shaping within the required band. The design is targeted for low power low IF receivers and it achieves a total power consumption of 1.7mW from 1.2V supply. The chip is fabricated with UMC 0.13μm technology.
