In this paper a high resistant EMI interference CMOS operational amplifier has been designed and simulated. It is designed by implementing easy modification of the differential pair with active current load. The power amplifier seems to be leading the output voltage power with respect to the input supply given, the two stage power amplifier was designed in this current technology and results ar...

In RFID reader systems, power amplifier plays a critical rule for efficiency enhancement. A high efficiency power amplifier may not only increase the life expectancy of portable RFID devices but also reduce the reliance on heat sinks. Heat sinks usually occupy plenty of space and lead to packing difficulties. A well-designed power amplifier with high efficiency and output power may also increas...

High power, broad bandwidth, high linearity, and low noise are among the most important features in amplifier design. The broad-band spatial power-combining technique addresses all these issues by combining the output power of a large quantity of microwave monolithic integrated circuit (MMIC) amplifiers in a broad-band coaxial waveguide environment, while maintaining good linearity and improvin...

The design of an integrated CMOS Power Amplifier (PA) for a Jet Propulsion Laboratory (JPL) Synthetic Aperture Radar (SAR) mission is studied. Although there are a number of PA class definitions and published circuits, designing a high efficiency RF PA is still a challenging job. In this thesis, the goal is full integration in Silicon-on-Sapphire (SOS) using on-chip spiral inductors/transformer...

In several reports issued previously, a theoretical analysis has been given for the steady-state operation of a vacuum-tube power amplifier with a complex load impedance* This theoretical work was checked experimentally with amplifiers operating in the steady state at low power levels. One application of an amplifier which sometimes must operate with a complex load impedance is in naval sonar e...

Tailoring the properties of driving laser to need applications often requires compromises among stability, high peak and average power levels, pulse duration, spectral bandwidth. For instance, spectroscopy with optical frequency combs in extreme/visible ultraviolet region a near-IR laser, therefore power, duration few tens fs, maximal available Contrarily, parametric conversion efficiency is hi...
