Параметричний аналіз частотно-селективного конвертера імпедансу сигнального перетворювача оптоелектронних сенсорів

Abstract

The issues of further development of frequency-selective optoelectronic sensor’s signal converters are considered. The basis of the proposed solutions of signal converter is the impedance converter which provides the inductive nature of the impedance of the photosensitive sensor load circuit and, hence, the suppression of DC component of the photocurrent. On the basis of parametric analysis using SPICE models the possibility of resonance characteristics formation of selective signal converter’s on the falling band of the operational amplifier’s frequency characteristic.
