A novel class-AB transconductance amplifier, suitable for the input stage of high slew rate CMOS operational amplifier is proposed. The proposed class-AB transconductor is realized from a differential pair of mixed translinear common-drain push-pull circuit. A high speed operational amplifier employing the proposed input stage and a complementary common –source high gain stage is presented. HSP...

In first stage of each microwave receiver there is Low Noise Amplifier (LNA) circuit, and this stage has important rule in quality factor of the receiver. The design of a LNA in Radio Frequency (RF) circuit requires the trade-off many importance characteristics such as gain, Noise Figure (NF), stability, power consumption and complexity. This situation forces designers to make choices in the de...

In this paper, we experimentally investigate the performance of an efficient high gain triple-pass L-band ErbiumDoped Fiber (EDF) amplifier structure with a single pump source. The amplifier gain and noise figure variation with EDF pump power, input signal power and wavelengths have been investigated. The generated backward Amplified Spontaneous Emission (ASE) noise of the first amplifier stage...

The design of a fully differential CMOS transconductance amplifier is presented in this paper. This amplifier is to be used in the first stage of a 13-bit pipelined A/D converter, and was designed to meet the necessary specifications at a minimum level of power consumption. The amplifier presented below was based on a two-stage design of a telescopic cascode input stage followed by a common-sou...

The excitation and suppression of asymmetric modes in a coaxial relativistic klystron amplifier (RKA) with cascaded single-gap bunching cavities are analyzed this paper. Through theoretical analysis simulated verification, we find that the have low external quality factors, same resonant frequencies, negative beam-loading conductance ratios so they easily excited by electron beam. To solve issu...

We describe a fully differential amplifier for oversampled A/D converter applications. This amplifier employs a single stage telescopic architecture using both N-type and P-type gain-boosting technique with capacitive feedback. This architecture offers extremely high gain, low noise, low power and the need for compensation. But the potential slow-settling problem due to the slow doublet should ...

1 This work was undertaken as the Electronics and Telecommunications Engineering degree Final Project of its two first authors. Abstract The design, implementation and performance tests of an Si LDMOS-Based power amplifier for UHF is presented. The amplifier, conceived for medium power GSM-900 base-station applications, consists of a Class-AB single stage circuit designed for maximum output pow...
