20100007538Flicker Noise Reduction in Continuous Time (CT) Sigma Delta Modulators (SDMS) - Embodiments of a system for processing a signal may include a receiver configured to receive an input analog signal and an up converter coupled with the receiver and configured to up convert the analog signal to an up converted analog signal. Embodiments may further include an amplifier coupled with the up converter and configured to amplify the up converted analog signal to generate an amplified signal and also a bandpass filter coupled with the amplifier and configured to filter the amplified signal to generate a filtered analog signal. According to embodiments, the filtered analog signal may be fed to a quanitizer of the ADC. Intermediate signals made thus avoid the flicker noise region typically associated with an integrator of the ADC and may minimize the quantization noise associated with converting higher frequency analog signals.01-14-2010
