This book features an extensive index and all Mathcad worksheets.
Vinyl is back, tubes/valves are back, on the high-end field
SMD-free analog amplification surpasses digitalized chains, and top
microphone manufacturers still set on good old op-amps or on fully
discrete BJT, FET, and/or tube-driven amplifiers. There is only one
problem that is not satisfyingly well solved by the manufacturers:
It is the noise production of the active components and the useful
reflection in simulation tools, in tables or graphs of the
datasheets/data books. Nowadays, mostly surrounded by many digital
helping tools, it makes sense using them—also by analog
aficionados. It saves cost and time simulating first before
spending money. Presented in this book the software tool LTSpice
which is the free software solution from Linear Technology (today
Analog Devices) that could also be used by full analog lovers to
simulate the noise production of their amplifier design. All we
need is the right creation approach to develop simulation models
for the active components. Inter alia this is already done for
tubes and BJTs in the 2nd editions of my “How to Gain Gain” and
“Balanced Phono-Amps” books. For op-amps, the missing
approaches are presented in the book on hand. It cannot be denied
that mathematical software like Mathcad is extremely helpful to
find the right equations for graphically presented noise curves
which we can find in the literature. Nevertheless, it also works
well with other types of math software to fulfill the parameter
needs of the here presented modeling approaches for the input
referred voltage and current noise of—not only—excellent
sounding vintage op-amps, applicable in the audio range from 1 Hz
to 100 kHz.
