Abstract

The invention relates to the technical field of integrating circuits, and specifically relates to a 0.2-order T-type fractional order integral circuit module. The circuit comprises static coarse compensation and dynamic fine compensation. The static coarse compensation and the dynamic fine compensation are both applied to the 0.2-order T-type fractional order integral circuit, the static coarse compensation is completed by an operational amplifier A1, the operational amplifier A1 is connected into a reverse-phase amplification circuit, the input of the operational amplifier A1 is grounded, andthe output of the operational amplifier A1 is connected with an A0 reverse-phase input end. The dynamic fine compensation is based on an S / H circuit, when an S / H operational amplifier SMP11 is in a non-integral state, offset voltage still existing after an integral operational amplifier A0 is subjected to static coarse compensation is taken out, and in the integral state, the offset voltage is fed back to the input end of the A0 through a relay switch. The zero drift value is reduced through static coarse compensation and dynamic fine compensation, the temperature drift effect is reduced, thestability is high, the structure is simple, and high creativity is achieved.

Description

technical field [0001] The invention relates to the technical field of integrating circuits, in particular to a 0.2-order T-type fractional-order integrating circuit module. Background technique [0002] Integrator circuits are mainly used in occasions such as waveform transformation, elimination of offset voltage of amplifying circuits, and integral compensation in feedback control. The resistance and capacitance of the circuit to realize the fractional order chaotic system are unconventional resistance and capacitance, which are generally realized by the method of series connection of resistance and parallel connection of capacitance. At present, the main method of realization is to use the existing resistance and capacitance combination method on the breadboard , this method has relatively low reliability and stability, and is prone to errors. In the patent document with the patent application number 201610118764.X, a 0.2-order Lorenz-type chaotic system circuit based on...
