Design a BJT Voltage Divider Bias circuit with a required target Q-point of IC = 1.5mA and VCE = 4.5V using a 9V supply. Show all calculations.
💡 Hint: Follow the design procedure step-by-step.
Given an N-channel JFET with IDSS = 3mA and VP = -2V, design a self-bias circuit aiming for a Q-point of ID = 1.5mA. Analyze how variations in IDSS might affect the Q-point.
💡 Hint: Look closely at how the self-bias provides feedback, stabilizing the ID.
