This paper presents selected design and operation details of a custom integrated neural chip. This neural processing chip is designed in the recent 0.18 μm, single poly, six-layer Copper Interconnect Technology. The chip realizes an architecture that achieves the task of autonomous-learning execution times in micro to milli seconds. The core consists of basic building blocks of 4-quadrant multi...

Fig.2 Amplifier under test. Amplifiers can operate in classes A, B, AB, C, D, E and F [2]. We tested class A amplifier made by „Microwave Power Devices“, Model: LWA 4690-1/1837, based on bipolar devices (Fig.2). Usually, 1dB compression point, gain and two-tone third-order intercept point are measured as the amplifier figure of merit. As specified by manufacturer, the frequency range of the amp...

THE BALANCED CURRENT AMPLIFIER A NEW PARADIGM FOR THE 21ST CENTURY In 1931 Loy Barton, a research worker employed by David Sarnoff , unearthed the paradigm that has dominated all electronic power amplifiers used for audio reproduction and industrial power to this present day. Many incremental additions have embellished Loy’s original invention since its inception. The embellishments have many n...

In terminals for free-space laser links, optical amplifiers boost transmit powers into the Watt range. As pre-amplifiers, they help obtaining sensitivities of a few ten photons/bit. Concepts and requirements for such applications are discussed. ©2005 Optical Society of America OCIS codes: (060.4510) Optical communications; (250.4480) Optical amplifiers

This paper presents a Temperature Control Circuit for a microhotplate based gas sensor fabricated in standard 0.35/0.18μm CMOS technology. The on-chip microhotplate provide very high temperatures (between 200oC and 400oC), which are necessary for the normal operation of metal oxide sensing layers. The complete temperature control circuit comprises of 10-bit A/D converter, low pass filter, two 1...

3-D W/T/P encoded signal transmitted over free space optical link under the effects of atmospheric turbulences i.e. haze, fog and clear weather. System performance is best when clear weather attenuation is considered (0.1dB/Km) and results degrades in case of Haze (4dB/Km) and worst in Fog (20dB/Km).This system analyzed at varied distance for all the three turbulences, also effect of amplifiers...

Piezoelectric actuators are widely used in smart materials for vibration and noise control, precision actuators, etc. [1]. These actuators are largely capacitive and the reactive power applied on them can go to several tens of Watts. High-voltage, high-power class-D amplifiers [2-5] are ideal drivers for such loads, because of their high power efficiency. Preferably, efficiency should be high b...

Ultra low-voltage (ULV) floating-gate (FG) differential amplifiers are presented. In this paper we present several different approaches to CMOS ULV amplifier design. Sinh-shaped and tanh-shaped transconductance amplifiers are described. Measured results are provided. Keywords— Floating-gate, low-voltage, low-power, lowvoltage amplifiers, analog floating-gate circuits.

This letter presents a novel cascade ΣΔ modulator architecture that employs inter-stage resonation to increase its effective resolution compared to traditional cascades while presenting very relaxed output swing requirements and, subsequently, high robustness to non-linearities of the amplifiers. In addition, the use of loop filters based on Forward-Euler integrators, instead of Backward-Euler ...
