A novel topology for translinear (TL) loops comprising of CMOS second generation current conveyors (CC-II) and diodes is proposed. The proposed methodology opens a new paradigm towards the design of static and dynamic TL circuits in CMOS technology. Simulation of a current multiplier and a log-domain integrator demonstrates the concept.
Tight coupling and directivity are always the desirable characteristics of the coupler. This paper proposes a novel tightly coupled directional coupler using defected ground structure by using synthesis method. This coupled-line structure has a rectangular ground-plane aperture and two inserted signal strips in the aperture to improve coupling strength… (More)
