  2. Operational amplifier - Wikipedia

    en.wikipedia.org/wiki/Operational_amplifier

    All amplifiers have finite bandwidth. To a first approximation, the op amp has the frequency response of an integrator with gain. That is, the gain of a typical op amp is inversely proportional to frequency and is characterized by its gain–bandwidth product (GBWP). For example, an op amp with a GBWP of 1 MHz would have a gain of 5 at 200 kHz ...

  3. Gain–bandwidth product - Wikipedia

    en.wikipedia.org/wiki/Gain–bandwidth_product

    For transistors, the current-gain–bandwidth product is known as the f T or transition frequency. [4] [5] It is calculated from the low-frequency (a few kilohertz) current gain under specified test conditions, and the cutoff frequency at which the current gain drops by 3 decibels (70% amplitude); the product of these two values can be thought of as the frequency at which the current gain ...

  4. Open-loop gain - Wikipedia

    en.wikipedia.org/wiki/Open-loop_gain

    The open-loop gain of many electronic amplifiers is exceedingly high (by design) – an ideal operational amplifier (op-amp) has infinite open-loop gain. Typically an op-amp may have a maximal open-loop gain of around , or 100 dB. An op-amp with a large open-loop gain offers high precision when used as an inverting amplifier.

  5. Op amp integrator - Wikipedia

    en.wikipedia.org/wiki/Op_amp_integrator

    Real op amps also have a limited gain-bandwidth product (GBWP), which adds an additional high frequency pole. Integration only occurs along the -20 dB per decade slope, which is steady only from frequencies about a decade above f cutoff {\displaystyle f_{\text{cutoff}}} to about a decade below the op amp's GBWP.

  6. Transimpedance amplifier - Wikipedia

    en.wikipedia.org/wiki/Transimpedance_amplifier

    The DC and low-frequency gain of a transimpedance amplifier is determined by the equation =, so = If the gain is large, any input offset voltage at the non-inverting input of the op-amp will result in an output DC offset. An input bias current on the inverting terminal of the op-amp will similarly result in an output offset.

  7. Operational amplifier applications - Wikipedia

    en.wikipedia.org/wiki/Operational_amplifier...

    where Z dif is the op-amp's input impedance to differential signals, and A OL is the open-loop voltage gain of the op-amp (which varies with frequency), and B is the feedback factor (the fraction of the output signal that returns to the input). [3] [4] In the case of the ideal op-amp, with A OL infinite and Z dif infinite, the input impedance ...

  8. Gain (electronics) - Wikipedia

    en.wikipedia.org/wiki/Gain_(electronics)

    The term gain alone is ambiguous, and can refer to the ratio of output to input voltage (voltage gain), current (current gain) or electric power (power gain). [4] In the field of audio and general purpose amplifiers, especially operational amplifiers , the term usually refers to voltage gain, [ 2 ] but in radio frequency amplifiers it usually ...

  9. Frequency compensation - Wikipedia

    en.wikipedia.org/wiki/Frequency_compensation

    In electronics engineering, frequency compensation is a technique used in amplifiers, and especially in amplifiers employing negative feedback.It usually has two primary goals: To avoid the unintentional creation of positive feedback, which will cause the amplifier to oscillate, and to control overshoot and ringing in the amplifier's step response.
