Abstract :
A High-Speed Multi-Bit Bandpass Continuous- Time Delta-Sigma Modulator is presented in this paper. This modulator samples at high-IF signals, performing the direct conversion in the modern RF front-end receivers. In order to improve the design flexibility, an advanced design methodology is used. This methodology is very interesting for complex mixed-signal IC design, since it combines behavioral models and transistor level models in the same environment, reducing the simulation time.
