In a p+n junction diode under reverse bias, the magnitude of electric field is maximum at
A. The edge of the depletion region on the p-side
B. The edge of the depletion region on the n-side
C. The p+n junction

To prevent a DC return between source and load, it is necessary to use
A. Resistor between source and load

C. Capacitor between source and load
D. Either A or B
Ce-cc for cascode ce-cb
gm=(2Idss/Vp)(1- Vgs/Vp)
gm=(2x2/4)(1- 2/4)
gm= 5.2
Please help if I am wrong
It might be ce-cc also
