employing a BIT with a dc current gain of 100. The collector resistance may be chosen to be 1 ka. You are provided with power supplies of +5 V. Determine the gain of your amplifier. Verify your answer. 4. Design a current source of magnitude 2 mA Use this current source to establish a common emitter amplifier, employing a BJT with a dc current gain of 100 and an Early voltage of 50 V. The collector resistance is to be an active load, using the same kind of transistors. If you are provided with power supplies of +5 V, determine the gain of your amplifier.
