Given two matched transistors in a current mirror, if one transistor has a beta of 100 and the other 120, analyze how this mismatch affects output current when the collector current is set at 1 mA.
💡 Hint: Evaluate based on the proportions created by their betas.
Design a common emitter amplifier using a current mirror with a target gain of 1000. Discuss which transistor parameters you would need to focus on to achieve this.
💡 Hint: Draw out your circuit to visualize how currents will need to flow and how adjustments will impact gain.
