A BJT circuit is designed with a VCC of 12V and has a target IC of 1mA. Calculate the voltage drops across the resistors if RE is chosen as 1kΩ. Analyze the impact on Q-point stability with this arrangement.
💡 Hint: Look for whether the Q-point can shift due to current changes.
In a JFET self-bias circuit, if IDSS is 2mA and VP is -1V, calculate the expected ID if VGS is measured at -0.5V. Discuss what adjustments you would take if this ID is much lower than expected.
💡 Hint: Reflect on how VGS influences ID as per Shockley's equation.
