Consider a forward-biased diode with a load resistance. Let the static volt-ampere characteristic of the diode be given by Equations, and typically represented by Figure.
(a) For a dc bias voltage VB, obtain the load-line equation and the operating (quiescent) point (IQ,VQ) by graphical analysis. Extend the graphical analysis for different values of (i) load resistance, and (ii) supply voltage.
(b) If, in addition to the constant potential VB, an alternating or time-varying potential vS(t) = √2 VSsin ωt is impressed across the circuit, discuss the dynamic (ac) characteristics of the diode in terms of (i) small-signal current and voltage waveforms, and (ii) large-signal current and voltage waveforms.
(i) Sketch a fully-labelled electro-pneumatic circuit showing your actuators in the START position and employ metered out speed control with mono-stable 5/2 DCV's having solenoid a
