Operational amplifiers and measuring transducers

The book discusses the properties of bipolar operational amplifiers, BiFET, CMOS, BiMOS and provides the most important information in the field of linear and non-linear measuring transducers. The amplifiers were also characterized: measuring, with the following minimization of the input voltage unbalance, with the isolation barrier, transconductance and transimpedance.

A methodology for determining errors of converters processing static and dynamic signals was presented. The effect of CMRR and SVRR coefficients, noise and finite amplifier amplification as well as the unstable resistance of negative feedback resistors were considered. Amplifier processing errors were also sensitized on a logarithmic scale in bits, facilitating comparison of amplifier parameters with A / C and C / A converter parameters.

In the part "nonlinear systems", functional systems that carry out operations of multiplication, division, root formation and exponentiation are discussed. The metrological features of the maximum, average and effective transducers described by explicit and entangled functions were analyzed. The principles of approximation and linearization of nonlinear functions are given.
