Table-based PWM for all-digital RF transmitters
(John Wiley & Sons Ltd, 2019-02)
In this paper, a novel pulse-width modulator (PWM) for an all-digital PWM transmitter based on switching amplification is presented. In this approach, each symbol is represented by a sequence of pre-computed PWM pulse ...
Baseband model for uniformly sampled RF-PWM
(Institute of Electrical and Electronics Engineers, 2020-03-12)
A baseband model for a polar RF modulator based on uniform sampling (US) pulse width modulation (PWM) is presented. RF-PWM allows to encode a complex baseband signal (amplitude and phase) into the pulse width and pulse ...
Symbol-rate Baseband Signal Model for RF Pulse-Width Modulation Transmitters
(Institute of Electrical and Electronics Engineers, 2021-06)
Aiming to shed light on the operation of fully-digital transmitters, we present the first symbol-rate baseband model that makes explicit the inter-symbol interference introduced by the RF pulse-width modulation (RF-PWM). ...

Diseño de un circuito micro electrónico para amplificar, modular y transmitir via rf la señal de un sensor de presión bio-mems
(2012-01-25)
En este trabajo se presenta el diseño y la simulación de un circuito integrado para
amplificar, modular y transmitir vía radiofrecuencia la señal eléctrica proveniente
de un sensor de presión arterial MEMS (Micro-Elect ...
Arquitetura de hardware multicanal reconfigurável com excitação multinível para desenvolvimento e testes de novos métodos de geração de imagens por ultrassom
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Elétrica e Informática Industrial, 2013-10-08)
Medical ultrasound (US) scanners are amongst the most sophisticated signal processing machines in use today. Even with the recent advances in electronic technology, their typical architecture is often “closed” and does not ...
