Abstract
- The class-E zero-voltage switching/zero-derivative switching operation within class-DE amplifiers can be easily achieved by adding external shunt capacitances. This paper gives the analytical expressions for the designs of the class-DE amplifiers with the shunt capacitances composed of linear and nonlinear capacitances for any grading coefficient m of MOSFET body junction diodes at the switch-on duty ratio D=0.25. In the analysis, an equivalent linear shunt capacitance of the nonlinear MOSFET drain–source parasitic capacitances is derived. Analytical results show good agreements with the simulation and experimental ones, which validate our analysis. [ABSTRACT FROM PUBLISHER]
