LECTURE  NOTES :




ASSIGNMENT - I (Theory) :



ASSIGNMENT - II (Problems) :



Previous JNTU Questions :

1. Discuss the effect of different type of loads to a common source MOS amplifier.

2. Differentiate between cascode and folded cascode configurations.

3. Draw the FET  amplifier equivalent circuit  looking into the drain  and find its gain & o/p impedance? 

4. Starting  with the definition of gm   and rd , show that  if two identical FETs  are connected  in parallel,  gm   is doubled and  rd   is halved since µ = rd gm , then  µ remains unchanged.
