Matching High-Speed Amplifiers and Data Converters
... R2 adds several terms that can, if you are not careful, dominate over the en term. So if a low noise amplifier was selected for its noise, setting R2 consistent with that will retain the original intent. R3 will also add noise in a similar fashion to R2 – it will turn out that setting R3 ≈ R2 is goo ...

VCA810 数据资料 dataSheet 下载
... Operating from ±5V supplies, the gain control voltage for the VCA810 will adjust the gain from –40dB at 0V input to +40dB at –2V input. Increasing the control voltage above ground will attenuate the signal path to greater than 80dB. Signal bandwidth and slew rate remain constant over the entire gain ...

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.
