Abstract: This paper presents an analysis of effect of inductor and switch losses on output power and efficiency of low power class-E power amplifier. This structure is suitable for integrated circuit implementation. Since on chip inductors have large losses than the other elements, the effect of their losses on efficiency has been investigated. Equations for the efficiency have been derived and plotted versus the value of inductors and switch losses. Derived equations are evaluated using MATLAB. Also, Cadence Spectre has been used for schematic simulation. Results show a fair matching between simulated power loss and efficiency and MATLAB evaluations. Considering the analysis, the proposed power amplifier shows about 13 % improvement in power effiency at 400 MHz and -2 dBm output power. It is simulated in 0.18 ?m CMOS technology.
