    A new design technique for a true rms-to-dc converter is implemented around a dual translinear-based squarer circuit. A dual translinear loop and current mirrors are the basic building blocks in this realization scheme, and the computation is carried in current-mode. The conversion circuit consists of a squarer, a low-pass filter and a square-root circuit. Since no rectifier function is required, this converter configuration enables us to obtain a wide-band frequency response. The input signal can be voltage or current. In addition, the modification of the converter to construct a vector summation computing circuit is also discussed. © 1998 IEEE.

    The current-controlled second order multifunctional filter is described. It uses only three current controlled conveyors and two grounded capacitors. Three types of current transfers, highpass, bandpass, and lowpass, can be acheived simultaneously and both ω<inf>0</inf>, and Q are electronically adjustable. The circuit can also be modified to be a current controlled oscillator. The simulated results are illustrated.

    Current controlled oscillator based on translinear conveyors

    A current controlled oscillator based on translinear current conveyors is presented. The oscillation frequency can be varied proportionally to the bias current. The oscillator uses two CCCII<sup>+</sup>s, and two grounded capacitors. SPICE simulation results agree with the theory.
