Abstract

Synthesis of variability of the operational amplifier circuit with low input offset voltage

  The paper discusses options for the synthesis of op-amp circuits, with the effect of their own compensation to the systematic component of the voltage offset and drift in temperature and radiation effects. In the analyzed operational amplifier without a significant increase in the number of elements significantly improved the accuracy of the static and the voltage gain in comparison with the basic scheme. The results of computer simulations have confirmed the qualitative analysis of the considered circuit design. The proposed options for the implementation of operational amplifiers based on different types of voltage-current converters allow the designer to synthesize electronic devices with desired accuracy and dynamic characteristics of the light conditions.

Keywords: operational amplifier, the synthesis, the offset voltage, the simulation, the inverter, the compensation
