Question

1. Look up in the dictionary the word quiescent. Then describe it using your own words.

2. A nonlinear device (diode D1N4002) is used in the circuit shown below. Determine the Q point, namely the quiescent current through, and the quiescent voltage across the diode. Use Load-line analysis (as demonstrated in class). A curve representing the characteristics of the diode is attached.

3. Use the Solver Add-in in EXCEL, to find the value of x which gives a y of 100, in the following function:

y= 3+5x^3+8x^5

Explanation / Answer

Quiescent current is the current drawn by a circuit when it is not amplifying a signal or driving a load (my definition, not an official definition).

I(q) of a DC-DC converter would be the current it draws when there is no load on the output so it is functioning (i.e., generating the desired output voltage), but is not supplying current to a load.

Same for an IC voltage regulator or an amplifier.

Think of it as the baseline current required to have the device ready to perform its task.
