Abstract

Earlier there were many circuits that were made using buffer technologies but no such matter exists which implemented five different buffers in any modulation circuit. The whole work is been divided into 3 basic section which is active balun, a buffer circuit, and complementary switches. 77 The active balun can have relatively less loss than a passive balun. We preferred active balun in the circuit due to its gain characteristics. In our circuit active balun consists of two MOSFETs applied in source and drain. The output obtained in the common source FET will have a phase shift of 1800 with the input and the output obtained in the common gate will have a phase shift of 00 or multiple of 3600. The input signal was passed to each of the tested buffers and the switching conditions were tested on each of them. CMOS, BiCMOS, FET, common collector, and opamp circuits were used for the switching condition and were later added with the active balun for the final result. The main reason for implementing these many signals was to get more accurate and correct results in a shorter period. Based on all the simulations and parameters. In this paper, we have further worked on different buffer technologies that were not included in previous works and have got various parameters to compare them and finally conclude which one is better. Also, we calculated the rise time and fall time of the buffers to compare the spontaneously they give results. Before plotting the graph and comparing different parameters we have taken different cases and at different input values.
