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)
Human visual systems maintain a stable internal representation of a scene even though the image on the retina is constantly changing because of eye movements. Such stabilization can theoretically be eeected by dynamic shifts in the receptive eld (RF) of neurons in the visual system. This paper examines how a neural circuit can learn to generate such shifts.… (More)
