PHD Thesis1 Abstract High-Speed, Low-Power Sigma-Delta Modulators for RF Baseband Channel Applications by Arnold R. Feldman Doctor of Philosophy in Engineering-Electrical Engineering and Computer Sciences University of California, Berkeley Professor Paul R. Gray, Chair Recent efforts in the design of integrated circuits for RF communication transceivers have focussed on achieving higher levels of integration as well as adaptability to multiple RF communication standards. Direct conversion and wideband IF double-conversion receiver architectures increase integration because channel select ltering may be performed on chip at baseband. To achieve adaptability to multiple communication standards, programmable channel select ltering can be more easily performed in the digital domain. A sigma-delta modu……
