Abstarct Amplification is one of the most basic and prevalent RF/Microwave circuit functions. This paper describes the design of an 11 GHz PHEMT ATF-36077 microwave amplifier. The amplifier is manually designed using conventional technique, Smith chart was used to do a matching of the input and output of the amplifier. A completed design of the amplifier was optimised using Hewlett-Packard Adva...

We demonstrate a high-power, picosecond, thulium-doped, all-fiber master oscillator power amplifier with average power of 120.4 W. The compact fiber oscillator is carefully designed with high repetition rate for the purpose of overcoming the detrimental effects of fiber nonlinearity in the later fiber amplifiers. The pulse duration of 16 ps at 333.75 MHz repetition rate results in a peak power ...

In recent years, there has been an increasing demand for high-speed digital circuits at low power consumption.

Class-E amplifier has the potential to deliver high efficiency required for the next generation wireless systems. In this journal, we discuss a novel load pull analysis technique to characterize the efficiency performance of Class-E amplifier in an outphasing power combining scheme. Class-E amplifier is not an ideal current or voltage source as is required for the traditional analysis of outpha...

In this paper a high speed hybrid current mode sense amplifier is presented. Sense amplifier is the most important component of SRAM cell used to sense stored data. Sense amplifiers are used to read the contents of SRAM cells. Sense amplifiers perform amplification, delay reduction and power reduction. Earlier voltage mode sense amplifiers are used to sense the data from bitlines. But with incr...

In this paper, a CMOS radio frequency (RF) multi-band band-pass amplifier using a high-Q active inductor load with a binary code band selector suitable for multi-standards wireless applications is proposed. By employing the improved high-Q active inductor including two bits binary controlled code, the RF multi-band amplifier operating at four different frequency bands is realized. The proposed ...

We demonstrate a new type of four-pass dye laser amplifier that can reduce the possibility of parasitic oscillation between optical components used in the amplifier. Pumping the amplifier with a 5.6-mJ Q-switched doubled Nd:YAG laser output, we obtain high-peak-power pulsed output of an incident cw narrow-bandwidth dye laser beam with a power gain greater than 2 x 10(6) . Subsequent amplificati...

power amplifiers (pas) are inherently nonlinear elements and digital predistortion is a highly cost-effective approach to linearize them. although most existing architectures assume that the pa has a memoryless nonlinearity, memory effects of the pas in many applications ,such as wideband code-division multiple access (wcdma) or orthogonal frequency-division multiplexing (ofdm), can no longer b...

Douglas Self’s writing on audio power amplifiers provides the reader with invaluable information. Not only does he teach the fundamentals (and details) of power amplifier design per se but also discloses a systematic approach to analyse the distortion performance of typical amplifier topologies. The latter is particularly important as systematics does not appear to be a natural thing in audio c...

The fundamental operating principle of a Class F power amplifier and the factors aiding or affecting Class F performance were explicated previously. A Class F power amplifier design which satisfies WCDMA specifications is explained in this paper. The Class F amplifier was designed by employing Motorola’s LDMOS (Laterally Diffused Metal Oxide Semiconductor) transistor models and we simulated its...
