  • Variable gain amplifier building blocks based on MOSFET current dependence on the drain to source voltage

    Publication Year: 2010, Page(s):19 - 24
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1172 KB) | HTML iconHTML

    This paper describes two variable gain amplifier building blocks which use MOSFETs operating in triode or saturation regions as basic transconductances. Employing two matched transistors that have all the terminals, except for the drain, connected together, one has the possibility of controlling the drain current using the drain voltage as a control. All the circuits were simulated using the austr... View full abstract»

    This paper describes the architecture of a time-multiplexed Programmable Array Logic (PLA) designed for structured ASIC technology. Time multiplexing is realized by storing sixteen PLA configurations in on-chip memory. This inactive an-chip memory is distributed around the chip allowing single cycle configuration change and it can be accessed either from off-chip or from internal logic. Functional...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1146 KB) | HTML iconHTML

    This paper presents an improved amplifier compensation scheme for driving large capacitive loads. The dual-path compensated amplifier topology requires two parallel high speed paths for signal propagation and offers better performances than previously reported compensation schemes. The goal of this work was to improve this type of architecture in order to achieve lower power consumption, bandwidth... View full abstract»

  • Optimization of the channel filter in OFDM radio receivers by using genetic algorithms

    Publication Year: 2010, Page(s):43 - 46
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1170 KB) | HTML iconHTML

    This paper proposes a novel method for deriving optimized transfer functions for channel filters in OFDM receivers with Zero Intermediate Frequency architectures. A genetic algorithm is employed, based on only three selection criteria that independently control the pass band and the stop band of the filter. Another special feature of this method is that the disruptive effect of the signals from th... View full abstract»

    This paper presents a way of increasing overall performance in embedded processors by introducing a multithreading interleaved execution model that can be applied to any Instruction Set Architecture. Usual acceleration techniques as superpipeline or branch prediction are not suited for embedded machines due to their inherent inefficiency. We will show that by removing dependencies within a process... View full abstract»

    This paper presents a macromodel of first generation current conveyor (CCI). This macromodel is suitable for fast simulations of integrated circuits containing current conveyors. The accuracy of the proposed macromodel has been verified by Spice simulations. The results show a close approximation with simulation on the transistor level but with reduced computer simulation time. View full abstract»

    In our days, almost all of the electrical equipment has been equipped with switching supplies which can cause disturbances in the electrical power network. In order to reduce or even eliminate this disturbances, an electrical power network monitoring is required. The disturbances presents in the system must be recorded and analyzed in order to take the right decision to eliminate them. View full abstract»

    An analytical method to determine the response of a class of Oscillation Based Test circuits built around second-order filters is presented. It is showed that in the case of a system with real poles the traditional setup for the Oscillation Based Test fails to oscillate. A novel circuit structure with a trigger-Schmidt comparator is proposed that circumvents this limitation. View full abstract»
