Load line Analysis

Posted by AJ × 23:53

• The applied load will normally have an important impact on region of operation of

device.

• If analysis is done in graphical approach, a line can be drawn on the characteristics of

the device that represents applied load.

• The intersection of load line with the characteristics will determine the point of

operation.

• Such an analysis is called as load-line analysis.

• The intersection point is called ‘Q’ point or operating point.

• Its very simple as compared to the non-linear analysis of diode which involves heavy

maths……

Both KVL and KCL must be satisfied at all times

i-v curves plotted for diode (energised by Vss)

We can combine these curves on one plot to do a load line analysis
