unit-1 diode

Across
5.	/ this circuit produces an output of 4 times of the peak input voltage
6.	/ the ac component present in the output of a rectifier
9.	/ this region is devoid of charge carriers
10.	/ it clips both positive and negative cycles of a signal
12.	/ the barrier potential offers opposition to these carriers in a diode
13.	/ the capacitance existing in a reverse biased diode
14.	/ this level lies in the middle of conduction band and valence band in an intrinsic semiconductor
15.	/ it shifts a signal to a different dc level

Down
1.	/ this band is nearly empty in a semiconductor
2.	/ it converts ac voltage to unidirectional voltage
3.	/ Ge acts like this at zero degree kelvin
4.	/ the magnitude of reverse saturation current depends on this
7.	/ it is used as a p-type impurity
8.	/ an ideal diode offers this resistance when it is reverse biased
11.	/ the process of connecting a battery across the pn junction
