Analytical Design Equations for Class-E Power Amplifiers [PDF]
IEEE Transactions on Circuits and Systems I: Regular Papers, 2007 This paper presents the analytical solution in time domain for the ideal single-ended Class-E Power Amplifier (PA). Based on the analytical solution a coherent non-iterative procedure for choosing the circuit parameters is presented for Class- E PA’s with arbitrary duty-cycle and finite dc-feed inductance (e.g.
