In this study, a novel Lyapunov function-based robust nonlinear proportional–integral (PI)-
type controller for regulating the output voltage of the direct current to direct current (DC–DC) …

This paper presents an all-digital transmitter solution particularly suited for Massive multiple-
input and multiple-output (MIMO) systems for mobile communications. Massive MIMO is a …

In high-speed cutting processes, late replacement of defective tools may lead to machine
breakdowns and badly affect the product quality, which subsequently lead to scrap parts and …

This paper presents a novel multilevel radio frequency (RF) pulsewidth modulation (PWM)
method for all-digital transmitters (ADTx) that actively eliminates the selected harmonics of …

This paper presents a frequency-domain analysis of the noise and distortion terms produced
by a digital RF modulator that uses pulse width modulation (PWM) for the amplitude …

A novel pulse-width modulation (PWM) architecture for all-digital transmitters (ADT) that
achieves good in-band and out-band performance with a very low ratio between the …

This work studies the spectrum of discrete-time Uniform-sampling pulse width modulation
(UPWM) signals originating from stochastic input signals. It demonstrates that for ergodic …

This brief presents a pulse-modulated polar transmitter using direct digital synthesis (DDS)
for 5G NR mobile phone applications. In contrast to the conventional radio-frequency …

A fully digital 0.9 GHz-2.6 GHz multimode modulator based on the principle of RF-PWM is
presented. It makes use of a delay-line based phase modulator which delays an incoming …

This paper presents an all-digital polar pulsewidth modulated (PWM) transmitter for wireless
communications. The transmitter combines baseband PWM and outphasing to compensate …
