Question 1
Given a fixed bias CE amplifier with a supply voltage of 15V, a beta of 100, and a collector resistor of 2 kΞ©. If the beta changes to 300, what would be the new collector voltage and current if the design allows?
π‘ Hint: Use the voltage drop formula and ensure you consider the voltage limit to avoid saturation.
Question 2
Design a circuit with a cell bias configuration that maintains a collector current of 3 mA. List the resistors needed to achieve this with a supply voltage of 10V and react to varying beta.
π‘ Hint: Apply the cell bias rationale to increase stability across varying beta.
