Most oscillator circuits include a nonlinear amplitude control that sustains oscillations at a desired amplitude with minimum output distortion. One approach uses the output sinusoid's amplitude to ...

Operational amplifiers (commonly called op amps) are a ubiquitous building block for designing electronic circuits. Today, these devices are fabricated as small integrated circuits, but the concept ...

This file type includes high-resolution graphics and schematics when applicable. Measuring the signals from extremely high-impedance sensors is a difficult task. Such sensors can have output ...
