WebBelow 3 MHz (or above, depending on the device and the operating conditions), the device has a fixed current gain. For frequencies above 3 MHz, the gain rolls off. At 30 MHz, you would expect a minimum current gain of 300 MHz / 30 MHz = 10. Your mileage WILL vary.

Understanding and Applying Current-Mode Control Theory

WebIf the open-loop gain decreases due to frequency or the effects of system ageing, providing that βG is still relatively large, the overall system gain does not change very much. So negative feedback tends to reduce the effects of gain change giving what is generally called “gain stability”. Example No1. A system has a gain of 80dB without ...

Loop Gain and its Effect on Analog Control Systems

WebThe open-loop gain falls at 6 dB/octave. This means that if we double the frequency, the gain falls to half of what it was. Conversely, if the frequency is halved, the open-loop gain will double, as shown in Figure 1-8. This gives rise to what is known as the Gain-Bandwidth Product. If we multiply the open-loop gain by the frequency, the ...
