Operational Amplifier - Historical Timeline
... An op-amp, defined as a general-purpose, DC-coupled, high gain, inverting feedback amplifier, is first found in U.S ... It had a single inverting input rather than differential inverting and non-inverting inputs, as are common in today's op-amps. 1947 An op-amp with an explicit non-inverting input ...
Implementation - Op-amp Implementations - Non-inverting Schmitt Trigger
... It adds a part of the output voltage to the input voltage thus "helping" it during and after switching that occurs when the resulting voltage is near the ground ... respect to ground) so, the circuit does not need an amplifier with a differential input ... Since conventional op-amps have a differential input, the inverting input is grounded to make the reference point zero volts ...
Implementation - Transistor Schmitt Triggers - Classic Emitter-coupled Circuit
... Q1 acts as a comparator with a differential input (Q1 base-emitter junction) consisting of an inverting (Q1 base) and a non-inverting (Q1 emitter) inputs ... The input voltage is applied to the inverting input the output voltage of the voltage divider is applied to the non-inverting input thus determining its ... over the upper legs of the voltage divider and changes the threshold in a different (to the input voltage) direction ...
Crossover Distortion - Possible Solutions
... By comparing the output to the desired output, and adjusting the input to correct for any error, we can significantly reduce distortion ... In an ideal model, the output of the op amp is held such that both inputs of the op amp must be at exactly the same voltage ... In this case, since the inverting input is directly connected to the output, the voltage at the non-inverting input is always equal to the voltage at the output and inverting input, hence eliminating distortion ...
Current-feedback Operational Amplifier - Operation
... shown, the section marked in red forms the input stage and error amplifier ... The inverting input (node where emitters of Q1 Q2 are connected) is low-impedance and hence sensitive to changes in current ... used instead of passive resistive biasing, and the non-inverting input may also be modified to become low impedance like the inverting input in order to minimise offsets ...

Famous quotes containing the word input:

    Celebrity is a mask that eats into the face. As soon as one is aware of being “somebody,” to be watched and listened to with extra interest, input ceases, and the performer goes blind and deaf in his overanimation. One can either see or be seen.
    John Updike (b. 1932)
