According to the structures and characteristics of the current conveyor circuits, a non inverting current integrator, an inverting current integrator and a multi output follower circuits have been constructed. Applying inter reciprocity network theorem, a method was developed to implement the transform from RLC filter prototype circuits into active RC filter circuits, and finally into current mode filter based on current conveyor. The transfer functions and component sensitivities are common among them. It is effective in the processing of current mode analog signal, which is easy to implement. 展开更多

A complete state variable current-mode biquadratic filter built by duo-output CCII (DOCCII) with variable current gain is presented. All the coefficients of the filter can be independently tuned through the variable current gain factors of the DOCCII. Based on the principles upon which the general biquadratic filter was constructed, a universal electronically tunable current-mode filter is proposed which implements the low-pass, high-pass, band-pass, band-suppress and all-pass second order transfer functions simultaneously. The PSPICE simulations of frequency responses of second-order filter of are also given. 展开更多

This paper introduces a mixed-mode biquadratic circuit employing DVCCs (differential voltage current conveyors) and grounded passive components. The biquadratic circuit can perform mixed-mode operation selecting the input and output terminals. And the circuit enables LP (low-pass), BP (band-pass), HP (high-pass), BS (band-stop) and AP (all-pass) transfer functions by suitably choosing the input terminals. The circuit parameters o30 and Q can be tuned orthogonally through adjusting the passive components. The biquadratic circuit enjoys very low sensitivities with respect to the circuit components. The achievement example is given together with simulation results by PSPICE. 展开更多

The filter only consists of minimum CCII elements and grounded resistors and capacitors. The topology is really simple, and the sensitivity is really low, so it suits full integration. The non idealities of the CCIIs are discussed and the compensations are given. The computer simulation of the transistor level is carried out and the results show that the proposed circuits are effective. 展开更多
