چکیده

A circuit technique to correct Vdd/PM distortion and improve efficiency as supply modulation of cascode class-E PAs has been proposed. The experimental result shows that the phase distortion can be improved from 20 degrees to 5 degrees. Moreover, a system co-simulation result demonstrated that the EVM can be improved from −17 dB to −19 dB. key words: envelope elimination and restoration (EER), polar system, class-E power amplifier, orthogonal frequency division multiplexing (OFDM)

A Hysteretic Two-phase Supply Modulator for Envelope Tracking RF Power Amplifiers

In this paper a two-phase supply modulator suitable for envelope tracking power amplifier is presented. The designed supply modulator has the linear assisted switching architecture. Two-phase architecture is used in order to reduce the output switching ripples. The proposed architecture uses hysteretic control instead of pulse width modulation (PWM) which significantly reduces the circuit compl...

Behaviors of EER Transmitter with Class-E Amplifier due to MOSFET Parasitic Capacitances

The class-E amplifier [1]-[11] is remarked as the next candidate of digital wireless power transmitters. Non-switching power amplifiers suffer from low power-conversion efficiency due to their inherent power loss in high back off area. Hence, switching power amplifiers such as class-D and E are remarked as a remedy for improving power-conversion efficiency and prolonging battery lifetime of por...

A hybrid Cartesian loop and envelope modulated PA linear transmitter architecture

A high efficiency and linearity P A solution is presented based on hybrid linearisation schemes that employ complementary techniques to overcome the weakness (or constraints) of either method on its own. I n particular, the high linearity of Cartesian loop is combined with the high efficiency of Envelope Elimination and Restoration (EER). The results of a prototype hybrid linearised PA built us...
