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. WebAnswer: When a signal needs gain, an amplifier is the component of choice. The ratio of the feedback and gain resistors, R F /R G, for a voltage feedback and a fully differential amplifier, determines the gain. Once the ratio is set, the next step is … WebNov 26, 2013 · If you increase frequency, is there a point where it affects the potential difference in the circuit. Frequency can change the relative resistance (called reactance) of various components, so strictly the answer is yes.
