generator for electric vibration with a feedback amplifier and oscillator workingEARL WERNER,RICHARD
You still have to be careful; the feedback path has to be kept electrically short or you may get positive feedback as you go up in frequency and create an oscillator. Update July 2023: These comments came from David: I spotted an error in the final paragraph of the Feedback Amplifier ...
This current-feedback operational-amplifier Based oscillator is used as a component for a capacitive, resistive and capacitive-resistive sensor electronic interfacing circuit.doi:US8860518 B1Muhammad Taher Abuelma'attiZainulabideen Jamal KhalifaUSJournal of Active & Passive Electronic Devices...
Figure 2.6.Block diagram of a sinusoidal feedback oscillator Thus, in order to produce and sustain an oscillation, this network must be supplied with external energy. This role can be ensured by anamplifier circuit, for example. Thelimitercircuit stabilizes the amplitude of the output signal at ...
Systems with positive feedback are found, nonetheless, in oscillator circuits where the amplifier produces its own input signal via a positive feedback loop.

The feedback in which the feedback energy i.e., either voltage or current is out of phase with the input and thus opposes it, is called asnegative feedback. In negative feedback, the amplifier introduces a phase shift of 180ointo the circuit while the feedback network is so designed th...
