Abstract
In this paper a new cascode class E power amplifier with a driving stage of class F and novel output network is
proposed. Class F power Amplifier is able to produce square waves, used in driving of main stage, owing to use main
frequency and third frequency harmonic. The proposed output network has also improved the parameters of circuit
like efficiency, power added efficiency and output power with adding a capacitor and an inductor. In order to have
more real results the circuit has been redesigned and simulated using spiral inductors.
The simulation has taken place using 0.18 μm CMOS technology in ADS simulator software based on IEEE 802. 11b
utilized in 2.4 GHz and WLAN applications. Proposed circuit delivers 23.1 dBm power; out of a 1.8 supply voltage to
a 50Ω load with 84.3% efficiency and 80.4 % power added efficiency in 2.4 GHZ operating frequency.
