  2. Diode modelling - Wikipedia

    en.wikipedia.org/wiki/Diode_modelling

    The Shockley diode equation relates the diode current of a p-n junction diode to the diode voltage .This relationship is the diode I-V characteristic: = (), where is the saturation current or scale current of the diode (the magnitude of the current that flows for negative in excess of a few , typically 10 −12 A).

  3. Shockley diode equation - Wikipedia

    en.wikipedia.org/wiki/Shockley_diode_equation

    Shockley derives an equation for the voltage across a p-n junction in a long article published in 1949. [2] Later he gives a corresponding equation for current as a function of voltage under additional assumptions, which is the equation we call the Shockley ideal diode equation. [3]

  4. Thévenin's theorem - Wikipedia

    en.wikipedia.org/wiki/Thévenin's_theorem

    The answer is not obvious, since the terminal voltage will not be V θ after Z e is connected. Instead, we imagine that we attach, in series with impedance Z e, a source with electromotive force E equal to V θ but directed to oppose V θ, as shown in Figure 2b. No current will then flow through Z e since E balances V θ.

  5. Load line (electronics) - Wikipedia

    en.wikipedia.org/wiki/Load_line_(electronics)

    The characteristic curve (curved line), representing the current I through the diode for any given voltage across the diode V D, is an exponential curve. The load line (diagonal line) , representing the relationship between current and voltage due to Kirchhoff's voltage law applied to the resistor and voltage source, is

  6. Modified nodal analysis - Wikipedia

    en.wikipedia.org/wiki/Modified_nodal_analysis

    DAEs assume smooth characteristics for individual components; for example, a diode can be modeled/represented in a MNA with DAEs via the Shockley equation, but one cannot use an apparently simpler (more ideal) model where the sharply exponential forward and breakdown conduction regions of the curve are just straight vertical lines.

  7. How to Solve It - Wikipedia

    First, you have to understand the problem. [2] After understanding, make a plan. [3] Carry out the plan. [4] Look back on your work. [5] How could it be better? If this technique fails, Pólya advises: [6] "If you cannot solve the proposed problem, try to solve first some related problem. Could you imagine a more accessible related problem?"
