AN-669: Effectively Applying the AD628 Precision Gain Block (英文 )
... The circuit in Figure 3 is a modification of the basic ADC interface circuit. Here, two-pole low-pass filtering is added for the price of one additional capacitor (C2). As before, the first pole of the low-pass filter is set by the internal 10 k resistor at the output of A1 and the external capacit ...

What are clippers circuits?
... Section (b) shows the same clipper configuration as it is shown in (a).but the diodes is replaced with its equivalent circuit model. When the input signal goes positive, the anode terminal of diode attains a higher potential than cathode. This makes the diode forward biased. The diode in reverse bia ...

Negative feedback
Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.Whereas positive feedback tends to lead to instability via exponential growth, oscillation or chaotic behavior, negative feedback generally promotes stability. Negative feedback tends to promote a settling to equilibrium, and reduces the effects of perturbations. Negative feedback loops in which just the right amount of correction is applied with optimum timing can be very stable, accurate, and responsive.Negative feedback is widely used in mechanical and electronic engineering, but it also occurs naturally within living organisms, and can be seen in many other fields from chemistry and economics to physical systems such as the climate. General negative feedback systems are studied in control systems engineering.
