In modern mobile communication systems, spectral efficient modulation formats have been
widely used, which results in the envelope of the radio frequency (RF) signal is variable and …

The explicit model predictive control (MPC) can solve the piecewise control laws offline to
save online implementation burden. However, many offline control laws have to be stored to …

The continuous demand of increasing data rates provided by wireless communication
systems is contributing to saturating the RF spectrum. Visible light communication (VLC) …

This paper presents an envelope tracking (ET) transmitter architecture based on the
combination of a novel 3-bit (N= 3) supply modulator and digital predistortion (DPD). The …

A dc-dc power converter based on a two-phase synchronous buck converter that reproduces
single-carrier digital modulation schemes by controlling the first switching harmonic of the …

The use of techniques such as envelope tracking (ET) and envelope elimination and
restoration (EER) can improve the efficiency of radio frequency power amplifiers (RFPA). In …

In recent years, there has been a great effort in the development of fast and efficient DC/DC
converters in order to follow the envelope of communication signals for increasing the …

The efficiency of linear power amplifiers can be improved by modulating its supply voltage
according to the peak value of the signal that is being amplified in a technique usually …

This paper presents the design of a linear-assisted hybrid DC-DC power converter for
envelope tracking RF power amplifiers. To jointly leverage the high efficiency of switch …

In this paper, the two-input buck converter is proposed as the dc/dc stage for photovoltaic
(PV) cascaded converters. This converter is attractive for this application because it is cost …
