(Use DC sweep to find out the diode’s turn-on voltage (Von).
(b) For the circuit below, plot ID vs Vin as Vin increases from −2 V to 2V . Use the constant voltage drop model and the Von obtained in (a) to explain why the result is a linear increase rather than an exponential increase.
(c) For the circuit below, plot Vout vs time and Vin vs time on the same graph, when Vin = 2 sin(2π × 100 × time). Use the constant voltage drop model and the Von obtained in (a) to explain the result.
(d For the circuit below, plot Vout vs time and Vin vs time on the same graph, when Vin = 2 + 0.01 sin(2π × 100 × time). Use the constant voltage drop model and the Von obtained in (a) to explain the result.
