A proof-of-concept superregenerative QPSK transceiver
López Riera, Alexis; Palà Schönwälder, Pere; Bonet Dalmau, Jordi; Moncunill Geniz, Francesc Xavier; Águila López, Francisco del; Giralt Mas, Ma. Rosa (2014)
Comunicació de congrés
Accés obertIn this paper we present a description and experimental verification of an HF-band proof-of-concept superregenerative transceiver for QPSK signals. We describe a simple implementation of an all-digital, FPGA-based, QPSK ... -
Signal and noise power spectra in superregenerative oscillators
Bonet Dalmau, Jordi; Palà Schönwälder, Pere; Moncunill Geniz, Francesc Xavier; Águila López, Francisco del; Giralt Mas, Ma. Rosa (Institute of Electrical and Electronics Engineers (IEEE), 2019)
Comunicació de congrés
Accés obertThis paper presents a method to quantify noise in superregenerative oscillators. A frequency domain technique, originally intended to determine the signal response, can also be used to determine the noise response. This ... -
Steady state analysis of class-E amplifier with non-linear capacitor by means of discrete-time techniques
Águila López, Francisco del; Palà Schönwälder, Pere; Bonet Dalmau, Jordi; Giralt Mas, Ma. Rosa (The Institute of Electrical and Electronics Engineers, 2000)
Text en actes de congrés
Accés obertA new method to determine the steady state response of switched nonlinear circuits is proposed. The method is based on a Gear discretization of the circuit equations. Additional samples of the waveform are used to describe ... -
Sub-nanosecond pulse filtering and amplification through firts-order controlled circuit instability
Moncunill Geniz, Francesc Xavier; Palà Schönwälder, Pere; Bonet Dalmau, Jordi; Águila López, Francisco del; Giralt Mas, Ma. Rosa (2009)
Comunicació de congrés
Accés obertIn this paper we investigate how to use controlled circuit instability in the filtering and amplification of narrow pulses. The basic circuit consists of a first-order RC network coupled to a negative resistance controlled ... -
Superregeneration revisited: from principles to current applications
Palà Schönwälder, Pere; Bonet Dalmau, Jordi; Águila López, Francisco del; Moncunill Geniz, Francesc Xavier; Giralt Mas, Ma. Rosa (2020-02-01)
Article
Accés obertWireless communications play a central role in our modern connected lives; at the same time, they constitute a very broad and deep area of research. The elements that make wireless communications possible are a transmitter, ... -
A superregenerative QPSK receiver
Palà Schönwälder, Pere; Bonet Dalmau, Jordi; Moncunill Geniz, Francesc Xavier; Águila López, Francisco del; Giralt Mas, Ma. Rosa (2014-01)
Article
Accés obertIn this paper we present a description and experimental verification of a superregenerative receiver (SR) for QPSK signals. Exploiting the fact that a conventional SR generates pulses which preserve the input phase ... -
Superregenerative reception of narrowband FSK modulations
Palà Schönwälder, Pere; Bonet Dalmau, Jordi; López Riera, Alexis; Moncunill Geniz, Francesc Xavier; Águila López, Francisco del; Giralt Mas, Ma. Rosa (2015-03-01)
Article
Accés obertIn this paper we investigate the possibilities of narrowband FSK detection using a superregenerative (SR) receiver. Previous SR FM demodulation techniques rely on detecting the amplitude variations caused by the different ... -
Tecnologías complementarias: dos asignaturas del nuevo grado en ingeniería de sistemas TIC enfocadas a las competencias genéricas
Escobet Canal, Teresa; Giralt Mas, Ma. Rosa; Palà Schönwälder, Pere; Vila Marta, Sebastià; Argelaguet Isanta, María Rosa (2011)
Comunicació de congrés
Accés obertEn el marco de la adaptación de las titulaciones al EEES, en la EPSEM se decidió impartir el grado en ingeniería de sistemas TIC. Este nuevo grado tiene por objetivo formar profesionales con un perfil generalista e ... -
