The thesis focuses mainly on well efficient model of high frequency range, low power and high stability all pass filters. In vision of the modern communications there is a progressive development in the signal transmission techniques in sight of the contemporary methods arise to transference the signal from source to destination by means of the transmitters and receivers, as the par expansion of these systems is more, transreciever has to be replaced both and in designing such complex model a number of suitable considerations are come into account like filtering the signal and passing the signal form Hz to several GHz mainly for the RF, military application and also for wireless communications. To accomplish the task for building an effective such a novel design is required for the processing and passing the sustainable measured quantity without any loss of the information and its characteristics are to be analysed for the accuracy and efficiency. In context of these a physical variable is needed for such type of realizations, and from these aspects an all pass filter design here provides all the features like gain, stability and phase, The implementation of the all pass filters is worked out with different methodologies and the selection of the topology for the high range frequencies are somewhat critical to validate. The models proposed accompanies the ideal characteristics of Analog all pass filter such as unity gain, high bandwidth and 180� phase shift over the band of frequencies with supressed noise and high efficiency.
