A novel low noise trans-impedance amplifier is proposed using low cost 0.18 µm CMOS technology. A resistive-capacitive feedback is used to extend the bandwidth of the amplifier. As the structure is inductor less, it is suitable for low cost integrated optical interconnects. In this paper Improved Particle Swarm Optimization have applied to determine optimal trans-resistance and noise of propose...

This paper presents a baseband predistorter to be used in OFDM systems operating with a nonlinear high power amplifier (HPA). Key features of the predistorter reside in the use of the HPA inverse structure as nonlinear distortion compensator. The performance of the compensated system is analyzed by simulations in an AWGN environment. The receiver also needs furthermore an equalizer in order to ...

A highly efficient class E power amplifier is demonstrated for application to wireless power transfer system. The amplifier is designed with an L-type matching at the output for harmonic rejection and output matching. The power loss and the effect of each component in the amplifier with the matching circuit are analyzed with the current ratio transmitted to the output load. Inductors with a qua...

This article proposed a simple self cascode RGC amplifier configuration to increase the gain and bandwidth. The cascode amplifier eliminates the miller capacitance between input and output and facilitates high gain, high input and output impedance with high bandwidth. However, the cascode amplifier requires relatively high supply voltage for proper operation and it decreases the output voltage ...

In this paper, the data predistorter with memory used to minimize total power consumption due to amplifier nonlinearity in single power mode quadrature amplitude modulation(QAM) systems is investigated. The design of the data predistorter (DP) with memory is independent of the operating optimality criterion but depends upon the operating point of amplifier nonlinearity. The more useful choice o...
