This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts.Explanation: Since at constant voltage drop model voltage drop across diode at forward bias is a constant. In this circuit if input is negative diode is reverse bias hence no current. So for negative input output is zero. For positive input V out will be equal to input with a voltage drop of V D.The Practical Diode Model or Constant Voltage Drop Model includes the barrier potential Forward-biased: diode is equivalent to a closed switch in series with a small equivalent voltage source (V F ) equal to the barrier potential (0.7 V) with the positive side toward the anode.
