Design of three new types of active quasi‐circulator modules

Abstract

Analysis and design of three novel active quasi-circulator modules are presented, which use the nonreciprocal properties of microwave unilateral power divider/combiner and amplifiers. These modules have many variations and can be used for very wide frequency range depending on the type of the unilateral amplifier used. Also, they can be used in MMICs as active circulators and also in other highfrequency applications.ABSTRACT: In this article, device characteristics of gate material engineered-trapezoidal recessed channel (GME-TRC) MOSFET are investigated using device simulators, ATLAS and DEVEDIT. Further, proposed device is examined for cutoff frequency (F T ) and parasitic capacitances, and result offers the opportunity for realizing the reliability of GME-TRC MOSFET for high-speed logic and RF applications.
