In the MOSFET amplifier shown in the fig. below, the transistor has $$\mu \,\, = \,\,50,\,\,{r_d}\,\, = \,\,10\,K\Omega ,\,\,{C_{gs}}\,\, = \,\,5\,\,pF,{C_{gd}}\,\, = \,\,1pF\,\,$$ and $${C_{ds}}\,\, = \,\,2\,pF.$$ Draw a small signal equivalent circuit for the amplifier for midband frequencies and calculate its midband voltage gain.

The frequency compensation is used in OP-Amps to increase its___________

Match the following.

GROUP-1
(A) Hartley
(B) Wein-bridge
(C) Crystal

GROUP-2

(4) Relaxation oscillator
(5) Nagative Resistance oscillator

A class-A transformer coupled, transistor power Amplifier is required to deliver a power rating of the transistor should not be less than.
