... The voltage gain of the VCA can be increased at the expense of bandwidth by changing the value of load resistors RL. Shorting RCM and increasing RL to 2k will increase the maximum gain by 20dB and the –3dB bandwidth will drop to approximately 10MHz. The LT1193 has a shutdown feature that reduces its ...

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.
