The circuit below has a variable voltage vin as its input. We are interested in Vout as a function of Vin. In other words, if we vary the value of the voltage source vin, what will be the effect on the voltage Vout? The steps below will help you to investigate this question, and your answers will form the basis for a new design. Assume that the diode can be sufficiently modelled as simple diode with forward voltage of 0.7 V (you do not need Shockley's equation). Vin 100Ω M Vf = 0.7 V 2 V V out
