A Class E Power Amplifier with Low Voltage Stress
A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...

متن کاملIdealized Operation of the Class E Tuned Power Amplifier
Absfracr-The class E tuned power amplifier consists of a load network and a single transistor that is operated as a switch at tbe carrier frequency of tbe output signal. ‘zbe most simple type of load network consists of a capacitor shunting tbe transistor and a series-tuned output circuit, which may bave a residual reactance. Circuit operation is determined by tbe transistor when it is on, and ...
متن کاملA Novel High Frequency, High-Efficiency, Differential Class-E Power Amplifier in 0.18μm CMOS
This paper presents the design of a high efficiency, low THD, 5.7GHz fully differential power amplifier for wireless communications in a standard 0.18μm CMOS technology. The power amplifier employs a fully differential class-E topology to achieve high power efficiency by exploiting its soft-switching property. In order to achieve high operating frequency, an injectionlocked oscillator is utiliz...
متن کاملA Practical Class S Power Amplifier for High Frequency Transmitters
Digital signal processing (DSP) techniques are being incorporated in the design of modern power amplifiers (PA) and as the speed of DSP advances it is envisioned that DSP will develop to a point where algorithms will provide signals at RF particularly for switching amplifiers. The digital transmitter has many potential benefits such as the absence of aging or tuning problems, reconfigurability,...
