    In 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 information, we take $N$ 1-bit samples of each generated pulse. A suitable choice of the sampling frequency gives as a result a bit vector containing a sub-sampled version of each PSK pulse. Extremely simple digital processing of the vectors from two consecutive pulses allows symbol decision, together with information on signal quality and frequency displacements. Although presented for the QPSK case, the principle may be applied to the M-PSK case with obvious changes. Experimental results on a 20 kbit/s proof-of concept receiver in the 27 MHz band, achieving a sensitivity of-103 dBm, with an FPGA-based implementation of the digital part, validate the proposed approach.

    This brief describes a superregenerative (SR) voltage-controlled oscillator as a building block for SR receivers where most of the oscillator spectrum components are outside the reception frequency band. This allows overcoming one of the main drawbacks of SR receivers, i.e., the potential interference to nearby receivers operating at the same frequency due to oscillator reradiation. We perform a qualitative analysis of the solution of the circuit equations, describe the most relevant parameters for design, and provide some numerical simulation results. Experimental results on a proof-of-concept implementation validating the described principle and a discussion of the observed behavior are provided.

    We present a simple receiver front end that makes use of the baseband superregeneration principle to detect ultrawideband (UWB) impulse radio signals. The UWB antenna is directly connected to the core circuit consisting of a resistor-capacitor (RC) network coupled to a negative resistance that varies under the control of an external quench generator. Due to a step-recovery-diode quench shaper, 50-ps time-domain sensitivity windows are generated that filter the received pulses and reject noise and interference. The circuit achieves high gain, exhibits automatic gain control, and directly demodulates binary phase modulations.

    In this paper, we describe how an on-line resource, primarily intended to improve the proficiency in a foreign language, can also facilitate the understanding of the symbolic language in an engineering degree course. We think that thanks to the use of this resource, a course in an engineering degree can tackle both the challenge of teaching symbolic language to non-native speakers and the challenge of doing this without losing insight into the concepts that appear in the course.

    Una de les característiques de l’Espai Europeu d’Educació Superior és la mobilitat de l’estudiantat i el professorat, entre diferents universitats i països, i la impartició d’assignatures en una llengua estrangera (AICLE), per tal de millorar la competència lingüística, una de les competències genèriques escollides per la universitat. En aquest context, el portal web Class-Talk ofereix fraseologia habitual a la docència universitària, de manera que es converteix en una mena de guia de butxaca al servei de la comunitat universitària en pro del multilingüisme. Aquesta guia de conversa va ser elaborada de manera conjunta entre professorat de l’EPSEM i tècnics lingüistes del Servei de Llengües i Terminologia de la UPC. És un recurs d’accés obert en línea, que conté unes 600 entrades classificades segons el seu ús habitual en el desenvolupament d’una classe, al laboratori, als exàmens, etc. en català, castellà i anglès, amb fitxers àudio associats. En aquesta comunicació descriurem el seu contingut i com es pot utilitzar com a recurs per a impulsar la impartició de docència en una altra llengua, alimentant l’autoconfiança de professorat i estudiantat.

    We focus on the goal of “Handling mathematical symbols and formalism” through the methodology of Content and Language Integrated Learning. The use of foreign language highlights, and possibly increases, the difficulties in the point of mathematical competence, but it can also be used to fix them. That is, making explicit the equivalence between formal and verbal language could improve symbolic language comprehension. Multilingual Formulae, an on -line resource at http://mformulae.epsem.upc.edu, is designed to give support in that direction, as equivalence is not found explicitly in textbooks or research papers. It contains sets of formulas with the corresponding written and oral version in several languages. The project, conducted by professors at the UPC Engineering School at Manresa Campus, is addressed to lecturers and students as a support to ensure effective communication when both Symbolic and Foreign language are used.

    In 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 by an external quench generator, which yields alternating periods of stability and instability. The study shows that when the circuit acts as a signal generator it can produce narrow exponential or Gaussian pulses, depending on the quench waveform applied. Included as a receiver front end, the circuit behaves as a highgain narrow-pulse filter. We also estimate the circuit parameters required to generate and receive sub-nanosecond pulses.

    This paper describes a bit-synchronous superregenerative receiver suitable for BPSK demodulation. The output of the superregenerative oscillator (SRO), which reproduces the phase information of the input signal, is directly sampled by a D flip flop clocked by a signal derived from the quench waveform. Analytical background on the response of the SRO to a BPSK modulated input is presented. A PSpice macromodel of the receiver is also provided, allowing simulation in the linear and logarithmic modes of operation. Simulation results confirm the feasibility of the described approach. Finally, a proof-of-concept superregenerative receiver, capable of receiving a BPSK modulated carrier at 27 MHz with preliminary experimental results is presented. The measured sensitivity of this receiver is –99.5 dBm for a bit error rate of 10-3..

    Nonlinear 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 series approaches are applied to the distortion of nonlinear switched circuits, the use of harmonic balance (HB) methods in nonlinear switched circuits seems to be marginal if not discarded. In this paper, we analyze the nonlinear class-E amplifier with an ideal switch by means of the HB method. We show how the switching function may be carefully chosen to improve the accuracy of the solution. When the circuit achieves actual class-E operation, the method converges better and is more accurate than classical timedomain methods. We conclude that the HB method is an alternative to time-domain methods that can be used to analyze the class-E amplifier in its expected operation mode.
