The following article contains detail description and introduction to **Power Amplifier Classification Circuit Diagram**. The main characteristics of an amplifier are Linearity, efficiency, output power, and signal gain. In general, there is a trade off between these characteristics. Higher efficiency leads to extended battery life, and this is especially important in the realization of small, portable products. Power amplifiers dissipate power and generate heat, which has to be removed. Due to the small size of integrated circuits, this is a challenging exercise in design and packaging. Several recent overview presentations have highlighted the special problems with achieving high efficiency and linearity in fully integrated power amplifiers.

Power amplifiers are grouped into classes depending on the nature of their voltage and current waveforms. The first major classes to be considered are class **A, B, D, E, F, and G amplifiers**. The class-A amplifier has the highest linearity over the other classes. It operates in a linear portion of its characteristic; it is equivalent to a current source.

One way to approach the nanoscale barriers of integrated circuit design or analysis is the RQT (relative quantum topological) atomic function for modeling at picotechnical scales. This produces a method for building the picoyoctometric 3D animated, interactive, silicon chip nanocircuit video model. The semiconductor based transistorized circuits may be simulated by building a model based on picometric atoms, and animated by application of momentum. Quantized thermic tints are imaged as intrinsic. Here is an explanation of the system.

The GT integral atomic topofunc is written by expanding the Schrodinger equation for one atom as a series differential within spacetime boundaries. While space is taken as bonded to psi by gravity, the atom pulsates at {Nhu=e/h} by relativistic {e-m(c^2)} pulsation cycles of nuclear radiation and absorption of force from the nucleoplastic surface layer. Psi pulsates inside limits of gravity and time. Quantum symmetry numbers are assigned along the series differential for nuclear change of mass to forcons by {e=m(c^2)} transform, with valid joule values, to give a topological wavefunction.

When the psi’s internal momentum function is written, rearranged to the photon gain rule, and integrated for GT limits, a set of 26 wavefunctions is found. Each is a topofunc for one of the atom’s 5/2 kT J internal heat capacity energy intermedon waveparticles, accounting for all of them. Those 26 energy values intersect the sizes for the fundamental physical constants: h, h-bar, delta, nuclear magneton, beta magneton, k. An exact 3D atomic video model image results.

The model displays force fields, and electromagnetic photons or laminar waves in picoyoctometric detail, giving a clear electron topological image as well. Images of the h-bar magnetic energy waveparticle of ~175 picoyoctometers (pyms) are available at http://www.symmecon.com.
