Abstract
Several design challenges of a low pass continuous time delta sigma modulator (LP DSM), to be used in switched mode transmitter architecture, have been identified. MATLAB simulations and modulation schemes for LP DSM have been presented. Various analog issues, mainly concerned with loop filter design, are discussed. Finally a highly efficient switched mode transmitter architecture using delta-sigma modulation and class-D amplifier is implemented. The transmitter architecture is operated at 200MHz.
