Implementation and study of high speed multimode digital modulator using ternary logic

Abstract

This paper presents a novel method for defining, analyzing and implementing a ternary based configurable digital modulator to realize amplitude, phase and frequency shift keying techniques. The proposed modulator is developed by ternary logic based combinational circuits such as ternary multiplexers, ternary decoders, standard ternary inverters for switching of three types of carrier signal .Ternary multiplexers are used as a basic building block for configurable modulator with the help of control logic. The architecture has been validated using standard EDA tool. The power dissipation of entire modulator for various modulation schemes, modulated waveforms and transient delay analysis for different carrier frequencies have been presented in detail.
