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 ... -

SNR measurement of superregenerative oscillators
Bonet Dalmau, Jordi; Palà Schönwälder, Pere; Moncunill Geniz, Francesc Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2021)
Text en actes de congrés
Accés obertIn this paper a method to measure the signal-to-noise ratio of superregenerative oscillators is presented. A spectrum analyzer can easily be coupled to a superregenerative oscillator without paying attention to possible ... -
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 ... -
Super-regenerative receiver for OFDM communication
Moncunill Geniz, Francesc Xavier; Bonet Dalmau, Jordi; Águila López, Francisco del; Demirkol, Ilker Seyfettin; Palà Schönwälder, Pere (Institute of Electrical and Electronics Engineers (IEEE), 2022)
Comunicació de congrés
Accés obertIn this paper, we demonstrate the suitability of the super-regenerative receiver in OFDM communication. The wellknown property of super-regenerative oscillators to preserve the amplitude and phase information is exploited ... -
Super-regenerative receiver wake-up radio solution for 5G New Radio communications
Moncunill Geniz, Francesc Xavier; Águila López, Francisco del; Demirkol, Ilker Seyfettin; Bonet Dalmau, Jordi; Palà Schönwälder, Pere (2023-12-14)
Article
Accés obertWake-up radio is a promising solution to reduce the energy wasted by mobile devices during an idle state. In this paper, we propose a new wake-up radio solution for 5G mobile devices based on a super-regenerative receiver ... -
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 ... -
The nonlinear class-E amplifier: a case study of harmonic balance applied to switched circuits
Bonet Dalmau, Jordi; Águila López, Francisco del; Moncunill Geniz, Francesc Xavier; Palà Schönwälder, Pere (IEEE Press. Institute of Electrical and Electronics Engineers, 2009-05)
Text en actes de congrés
Accés obertNonlinear switched circuits are usually analyzed in the time domain. The use of frequency-domain methods to analyze the steady-state of switched circuits is usually restricted to linear circuits and, although Volterra ... -
