The switching power amplifier is optimized based on the achievement of electromagnetic force, and the circuit structure of tristate power amplifier with soft-switching is designed. This circuit owns the advantages of reducing the dissipationpower on the power component and improving the speed of system dynamic response, enhancing the stability of the electromagnetic force in the final state, and the nice result is presented by the simulation. The small-signal model of the power amplifier is also established.

started with the analysis of characteristic parameter of the successive detection logarithmic amplifier,mainly discusses the main factor affecting its transfer characteristic by mathematics reasoning to its transfer function,studies the correlative relations of the single stair′s plus,the series with the dynamic range and the logarithmic precision by matlab and matrixx simulation.so two pieces of conclusion have been reached:one is on condition that the dynamic range is limited,the more the series that is used and the single stair′s plus is less,the higher the logarithmic precision is.the other is that using the double amplifier chain can enhance the logarithm starting point,so its stability is improved.and the conclusion has been applied to the practical circuit′s analysis of the tacan beaconing receiver.
