Design of Variable-Gain Current Conveyors
Several possible implementations of variable-gain current conveyors are proposed. They can be designed with two opamps and current mirrors and exhibit constant bandwidth property. Their configuration as differential-output current amplifiers is straightforward.
متن کاملAn Ultra-Low Power Variable Gain Current Mirror
A power efficient gain adjustment technique is described to realize programmable gain current mirror. The dissipation power changes over the wide gain range of structure are almost negligible. This property is in fact very interesting from power management perspective, especially in analog designs. The simple structure and constant frequency bandwidth are other ever-interesting merits of propos...
متن کاملFTFN with Variable Current Gain
This paper proposes a circuit configuration for the realization of a four-terminal floating nullor (FTFN) with electronically tunable current gain. It mainly consists of an op amp in input together with two complementary current mirrors with controlled gain and two standard improved Wilson current mirrors. The validity of the performance of the scheme is verified through PSPICE simulation resul...
متن کاملDesign of second-generation current conveyors employing bacterial foraging optimization
The present paper deals with the optimal sizing of CMOS positive second-generation current conveyors (CCII+) employing an optimization algorithm. A contemporary non-gradient stochastic optimization algorithm, called bacterial foraging optimization (BFO) algorithm, has been employed to obtain the optimal physical dimensions of the constituent PMOS and NMOS transistors of the CCII+. The optimizat...
متن کاملOn Multi-port Current Conveyors
A new terminology (order, kind, class) and the classification and definition of multi-port current conveyors are given. The generalized current conveyor is defined as a tool for synthesis. Several autonomous circuits containing multi-port conveyors are presented. The design of ARC oscillators and second-order filters based on the given autonomous networks is described in this paper.
