Unusual involvement of operational amplifiers for measurement purposes: non-inverting amplifier integral and derivative

摘要

This paper presents new possibilities for involvement frequency dependent circuits with operational amplifiers that are designed for use in measurement, low frequency and DC applications. Provide basic background, principles and equations for these circuits. This involvement should be used everywhere where it is necessary to process and edit analog electrical signal. The article presents and explains the involvement of various operational amplifiers explained the uses of operational amplifiers, allowing for the integral and derivative of the input voltage. Input voltage can be used and an optional large range of frequencies. All is used with single selectable passive impedance. The aim is to calculate and suggest such involvement, which processed do not invert phase voltage.
