Abstract:  In literature, it is widely accepted that the design of ClassE Power Amplifier (PA) with finite dc feed inductance requires a long iterative solution procedure. To avoid such iterative solution methods, analytical design equations should be known. The problem associated with the finite dc feed inductance ClassE PA is usually ascribed to the fact that the circuit element values are transcendental functions of the input parameters which is assumed to prevent the derivation of exact or fully analytical design equations. Using a proper analytical method, exact design solutions for ClassE PA with any inductor value can however be derived. A mathematically exact analysis of the idealized ClassE PA with finite dc feed inductance has been done and analytical expressions showing the relation between the circuit elements and the input parameters are found. These analytical expressions have been simplified to obtain explicit, relatively simple design equations. In this paper, we present these relatively simple design equations. Using these design equations, ClassE PA with finite dc feed inductance can be designed without iterative design procedures. The current paper discusses these simplified versions of the exact solution of general ClassE PA with finite dc feed inductance Key Words Power Amplifier, ClassE.
