Abstract

The work presented in this paper aims to develop an optimized switch mode power amplifier (OSMPA) using existing techniques in sigma delta (ΣΔ) architecture that will lead to the design of low cost, low power consumption transceivers with flexible frequency transmission. This design will allow all digital tunability and eliminate the need for cascaded analog components. The implementation will improve the output spectrum using the Cartesian ΣΔ structure by removing unwanted spectral components when the carrier frequency of the transmitted signal is changed. In addition, the new approach will improve the bandwidth and carrier frequency range by removing the noise and distortion products. Simulation results show that the new approach enables operation in the cellular frequency bandwidth with improved spectral efficiency.
