A classic analog application is the full-wave precision rectifier (absolute value) function. Many variations exist on this theme, each with its own supposed (often rather minor and sometimes downright ...
Current-mode full-wave rectifiers and precision rectification techniques represent vital advancements in signal processing, enabling the conversion of alternating current (AC) signals into a stable ...
A classic nonlinear analog function is the squaring circuit. It’s useful in power sensing, frequency multiplication, RMS computation, and many other odd jobs around the lab bench. Its input can accept ...
