Op amps are very high gain devices. To achieve stable operation, op-amps are used with negative feedback. The gain of the device alone is called open loop gain, and the gain when configuring a negative feedback circuit is called closed loop gain. Closed-loop gain is not device-specific ...

It is clarified that the optimal band-width of the low-pass filter can be determined so as to minimize the estimated model error bound in frequency domain. The proposed scheme can be extended to the closed-loop identification based on the fractional representation. 展开 ...

As previously noted, noise gain is simply the gain seen by a small voltage source in series with the op amp input; it is the ideal amplifier signal gain in the noninverting mode. If AVOL in Equation 1 and Equation 2 is infinite, the closed-loop gain becomes exactly equal to the noise...
We illustrate two differential oligopoly games using, respectively, the capital accumulation dynamics à la Nerlove-Arrow, and the capital accumulation dynamics à la Ramsey. We prove that these games benefit from the property that closed-loop memoryless solutions degenerate into open-loop solutions, si...
The impact of open-loop OP-AMP dynamic response on the design of high-frequency dc-dc switching regulatorsThis paper discusses the effects of open-loop gain of OP-AMPs on the transfer function of error amplifiers in feedback controlled switch-mode voltage regulators. It is shown that adequat...

closed-loop gain of the amplifier stabilized, eliminating the influence of the open-loop gain. Negative feedback also affects the amplifier’s input and output impedance. Voltage mixing increases the input impedance, current mixing decreases the input impedance; current sampling increases the output ...
