Many erbium doped fiber amplifier (EDFA) based multiwavelength optical networks employ techniques such as burst-switching or packet switching where the time interval between traffic blocks can be long enough to induce EDFA optical power transients. The optical power transients are created by abrupt changes in the average input power to the EDFAs and can adversely affect the performance of the n...

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 ...

This letter presents a new design method of a low-power transmitter for inductive link. The proposed method introduces the concept of class-F RF amplifiers into an inductive data link. The power dissipation of the class-F transmitter is analyzed for carrier and symbol transition. It is revealed that the proposed transmitter consumes extremely low power of less than 0.2 nJ/bit with BPSK modulati...

It has been shown [2] that adiabatic switching can significantly reduce the dynamic power dissipation in an integrated circuit. Due to the overhead in the realization of adiabatic logic blocks [3] the best results are achieved when it is used only for charging dominant loads in an integrated circuit [7]. It has been demonstrated [4] that a multi stage driver is needed for minimal power dissipat...

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...

Introduction Switching RF amplifiers appear to be a promising alternative for on-board transmit amplifiers due to its high efficiency and high isolation to neighboring elements [1,2]. We have shown that the current mode class-D amplifier (CMCD) allows a direct control of the current through the coil, resulting in a B1 field, which is potentially less sensitive to load changes than some other al...

In digital VLSI system the clock distribution network and flip flops are most power consuming components. The reduction of power consumption by clock distribution networks & flip flop makes the total VLSI system as low power VLSI system. In the earlier VLSI system design, different power consumption methods are followed to design the various flip-flops .The SABFF(sense amplifier based flip flop...
