New approach to preamplifier-shaper design
E. Atkin · Journal of Instrumentation · 2015
A new approach to the design of gain blocks (such as preamps, shapers) is described. The generalized block diagram and analytic expressions for its transfer function are presented. The particular cases of this structure are classical schemes, using either the voltage or current feedback, but not confined by them. The discussed formulas can be useful for the design of a whole range of amplifier blocks, built according to both the traditional and non-traditional structures. As result of an expression analysis the features of various particular cases are given. For example, those were confirmed by simulations and experimental data.
