This paper describes the improvement of an integrable fully-balanced wide-frequency current-turnable integrator with Caprio technique. The architecture of the circuit is relatively simple and symmetrical with different signals. The circuit of our interest are the integrator circuits as the basic functional circuit for current mode filters and the Caprio technique translated to integrator for an implementation of low input impedance differential current input. After the hand setting of the circuit parameters of Caprio technique, they were optimized to improve total harmonic distortion and intermodulation performance. The proposed conversion circuit is simple, very suitable for application and implementing. Experimental and simulation results found in a good with theoretical analysis are included. Streszczenie.

Introduction Integrators are most important circuits in many applications such as the integrated receivers [1], quadrature sinusoidal oscillators [2,3], digital modulators [4] and PID controllers [5]. It is usually desirable to have the fully balanced circuits with different signals [6,7]. The various techniques of differential integrator circuits have previously been reported in the literatures [1-9]. These techniques have many advantages such as linearity circuits, wide dynamic range, wide band, current tunable, simple circuit, low total harmonic distortion and low power consumption. Fully balanced techniques can suppress even order harmonics. However, such techniques total repeatedly suffered from high amplitude of even order harmonics and limited harmonic d[...]
