Abstract
A new analysis and synthesis method for continuous time bandpass Delta-Sigma (ΔΣ) modulators is presented in this paper. This method makes it possible to synthesize continuous bandpass ΔΣ modulators from discrete time topologies and it takes into account DAC+ADC delay and rise time. Theoretically, high loop delay can be achieved and non-ideal DAC can be used without effect on the performance of the modulator, if some special feedback schematics are used
