depuis la mort de samuel beckett en 1989, le théâtre de langue néerlandaise, tant aux pays-bas qu’en belgique, a manifesté un nouvel intérêt pour ses pièces. à la haye en avril 1992, lors du festival prestigieux consacré à l’auteur, nous pûmes assister à la représentation d’en attendant godot d’après la traduction de jacoba van velde, fidèle aux exigences de l’auteur. un an après, le ntg à gand...

Two bulk-driven CMOS (Complementary Metal Oxide Semiconductor) operational amplifier (op-amp) designs for electrocardiogram (ECG) application are presented and compared in this paper. Both op-amps based on two-stage amplification, where differential input is the first stage, while additional DC gain second stage. Different compensation techniques were integrated each op-amp design. Standard Mil...

In modern world of communication system, a coded M-ary pulse position modulation (PPM) scheme for transmitted reference ultra-wideband (TR-UWB) systems is proposed. The modulation level M in conventional M-ary PPM TR-UWB scheme, is defined only with a number of possible pulse positions Z. So, Z radio frequency (RF) wideband delay lines are required in order to map data bits into the proper puls...

As device size scales down, there have been challenges to design conventional analog circuits, such as low voltage headroom and the low intrinsic gain of a device. Although ever-decreasing device channel length in CMOS technology has mainly negative effects on analog circuits, it increases device speed and reduces the power consumption of digital circuits. As a result, time-based signal process...

Three circuit techniques are proposed that provide (with simultaneous use) an increase bymore than two orders of magnitude the maximum output voltage slew rate (SR) microelectronicoperational amplifiers (op-amps) based on bipolar transistors with a classical architecture,designed to operate in automatic control systems, radio engineering and communications, forexample, as drivers for ultra-high...
