Web14 Jan 2024 · Parasitic feedback. This is a parasitic coupling effect that creates additional positive or negative feedback to one terminal of an amplifier input. This purely unstable … Parasitic oscillation is an undesirable electronic oscillation (cyclic variation in output voltage or current) in an electronic or digital device. It is often caused by feedback in an amplifying device. The problem occurs notably in RF, audio, and other electronic amplifiers as well as in digital signal processing. It is one of the … See more Parasitic oscillation in an amplifier stage occurs when part of the output energy is coupled into the input, with the correct phase and amplitude to provide positive feedback at some frequency. The coupling can occur directly … See more Several measures are used to prevent parasitic oscillation. Amplifier circuits are laid out so that input and output wiring are not adjacent, preventing capacitive or inductive coupling. A metal shield may be placed over sensitive portions of the circuit. See more Feedback control theory was developed to address the problem of parasitic oscillation in servo control systems – the systems oscillated rather than performing their intended function, for example velocity control in engines.

Though sufficient to prevent the comparator from self-oscillating, such internal hysteresis can easily be swamped by any external noise of greater amplitude. In that case, you can improve performance by adding hysteresis externally. burberry polo for menWebParasitic turn-on effect An unwanted turn-on of a semiconductor switch can be caused by inductive as well as capacitive feedback to the gate.
