Distributed circuits using transmission lines (T-lines) or inductors exhibit high gain-bandwidth-products (GBW), as required by broadband communication systems. In this paper, the design of non-uniform downsized distributed amplifiers (DAs) is explored. Conventional DAs employ a topology in which inductors or T-lines separate the gain stages, yet the output currents from individual stages combi...

This paper presents a 60 GHz CMOS I/Q receiver for the high-speed wireless communication system. It consists of low noise amplifier, single-to-differential (S2D) passive mixer, buffer amplifier with generator, and wideband baseband (BBA) stage. The measured conversion gain 51 dB is achieved. bandwidth 300 MHz achieved from 57 to GHz. 90° tandem coupler was implemented signal generation, which h...

In this paper, the spectral behavior of a two-cell phase conjugated mirror (PCM)with a two-pass Nd:YAG amplifier has been analyzed experimentally and theoretically. For this purpose, amplifier input intensity for the three different states of laser oscillator with one, two and three longitudinal modes have been investigated. The numerical model is based on 2-dimension equations of stokes back-s...

Industry is continuously researching techniques to reduce power requirements, while increasing speed, to meet the demands of today’s low (battery) powered wireless systems. The operational transconductance amplifier (OTA) is a fundamental building block in analog (mixedsignal) design and its performance characteristics are the foundation of system level characteristics. Improving the performanc...

-In many digital Very Large Scale Integration design, clock system is one of the most power consumption component. It consumes 30% to 60% of the total system power. As we are in need to reduce the power consumption on portable digital circuit because power budget is severely limited on portable digital circuit. To achieve this requirement, a clock system employing two techniques such as Dual Ed...

For my final project, I will be constructing a 70V audio amplifier capable of delivering about 200 watts into a network of transformer coupled loudspeakers. My design utilizes a class G (rail switching) output stage for increased efficiency and lessened cooling requirements. The rest of the amplifier circuit is fairly standard: an input differential pair with negative feedback from the amplifie...

This paper describes the design and performance of an extremely low-noise differential transimpedance amplifier, which takes its two inputs from separate photodiodes. The amplifier was planned to serve as the front-end electronics for a highly sensitive shadow-displacement sensing system, aimed at detecting very low-level "Violin-Mode" (VM) oscillations in 0.4 mm diameter by 600 mm long fused-s...

Recording reliably extracellular neural activities is an essential prerequisite for the development of bioelectronics and neuroprosthetic applications. Recently, a fully differential, two-stage, integrating pre-amplifier was proposed amplifying then digitising signals. The amplifier featured finely tuneable offset that used as variable threshold detector. Given integrating, DC operating point k...
