The comparator is designed in pipelined ADC. FINFET is the technology which performs the dual gate MOSFET. This thesis focuses on the high-speed design of pipelined ADC. In the meanwhile, we try to minimize the power dissipation as well. In this thesis, A semidigital Gm-based amplifier is proposed for a low-power pipelined analog-to-digital converter (ADC )in HSPICE .And also we compare the pow...

A single-stage 24 GHz triple stacked power amplifier using 0.13 μm CMOS process is demonstrated. To Compare with parallel current combining method, series voltage combining method using a stacked amplifier architecture can realize a large output voltage swing from the top transistor without exceeding the transistor breakdown voltage limitations. However, at high frequencies, parasitic capacitan...

This paper explores the design of a Class-E amplifier with finite DC-feed inductance using three tuning methods. Furthermore, this work quantifies impacts process (referred to in as effect) on main figures merit (FoMs) amplifier. The goals were guarantee two conditions: zero voltage and derivative switching (i.e., soft-switching tuning). To best authors’ knowledge, systematic methods have not b...

We present a high power, single-frequency fiber amplifier based on master oscillator power amplification (MOPA) chains in all-fiber configuration. A 1.5 meter long highly doped Yb fiber with absorption coefficient as high as 16 dB/m at the 975 nm wavelength is used for the main power amplifier, no special assistant stimulated Brillouin scattering (SBS) suppression approach is employed. The maxi...

High Efficiency Power Amplifier for Envelope Detection is presented here in this paper which uses the LDMOS power amplifier to achieve high efficiency. The main objective in this work to design a power amplifier which is more efficient when subject to various kind of situations. QAM modulation with 64 point, and Additive White Gaussian Noise Channel was used here in this work. Amplitude Modulat...

A personal communications service/wide-band code division multiple access (PCS/W-CDMA) dual-band monolithic microwave integrated circuit (MMIC) power amplifier with a single-chip MMIC and a single-path output matching network is demonstrated by adopting a newly proposed on-chip linearizer. The linearizer is composed of the base–emitter diode of an active bias transistor and a capacitor to provi...

The CLW modulator represents the first successful application of high-power IGBT switching modules to meeting the requirements of multi-megawatt peak power modulators for microwave amplifier applications. Unlike some other solid-state modulators, no semiconductor switches are placed in series in this system. Neither are the switches connected in parallel. Rather, each switch drives a segment of...

34 LLE Review, Volume 65 A significant amount of hardware was added to OMEGA to upgrade it to a 30-kJ, 60-beam laser. To control this hardware, an entirely new control system was implemented. This article describes one of the core subsystems of that control system— the Power Conditioning Executive.1 Timing and control of the electrical energy fed to OMEGA’s amplifiers are provided by the power ...

We describe a Nd:YAG slab laser master oscillator power amplifier (MOPA) system that has been scaled to 104 W of output power at 1064 nm, single transverse mode. The amplifier system consists of rod amplifiers followed by edgeand end-pumped slab amplifiers. The MOPA output of 104 W was 89% fundamental TEM00 spatial mode with less than 3% depolarization. These results are a key milestone in the ...
