I know alpha should be around .9-1 but I don't think I know the formula for IB.
The common-base configuration is a type of transistor circuit in which the base terminal of the transistor is used as the input, while the collector and emitter terminals are the output. This configuration is commonly used in amplifiers and switches.
The alpha formula, also known as the current gain factor, is used to calculate the ratio of output current to input current in a common-base configuration. It helps determine the amplification capabilities of the circuit.
The alpha value is directly related to the gain of a common-base configuration. The higher the alpha value, the higher the gain of the circuit. A high alpha value indicates that the circuit is able to amplify the input signal with a small change in base current.
The IB formula is used to calculate the base current of a transistor in a common-base configuration. This information is important for determining the operating point of the transistor and ensuring that it is functioning within its safe operating range.
The common-base configuration offers several advantages over other configurations, such as high input impedance, low output impedance, and good stability. However, it also has a lower current gain compared to other configurations, making it less suitable for high-power applications.
