    Integrable Electronically Tunable Current Conveyors
    (1988-01-01)

    A generalised current conveyor, termed an electronically tunable second-generation current conveyor (ECCII), whose current-transfer ratio can be varied by electronic means, is introduced. A method is proposed for realising ECCII in monolithic integrated form providing both a positive and a negative ECCII in the same circuit. Experimental and simulation results demonstrating the circuit performance are included. Some simple applications which show that their circuit property can be varied by electronic means are also presented. © 1988, The Institution of Electrical Engineers. All rights reserved.

    Integrable wide-dynamic-range negative resistance circuits
    (1985-05-23)
    Surakampontorn, W.
    A technique for realising grounded and floating negative resistances in monolithic integrated form is described. The conversion circuit will linearly and accurately convert a given resistance to a corresponding negative resistance with exactly the same magnitude. The dynamic range of the converted resistance is approximately | V<inf>cc</inf> — 3V<inf>BE</inf>|. © 1985, The Institution of Electrical Engineers. All rights reserved.
