Si-50*10^3ohm-cm and ge-50ohm-cm

The answer is simple. Consider the PN diode for Ge 0.3eV is the breakdown voltage and in the case of Si its 0.7eV since the impurities are added in the same amount the bond due to the other atoms of the Si makes it resistive compared to the Ge.. thats all!

- Jun 24th, 2009
It is the combination?of both nMOS and pMOS, where the important thing is the source of the nMOS must be grounded & pMOS source is connected with VDD. Because nMOS is assert-low logic & pMOS is asssert-high logic.

What is the difference between Circuit Switching and Packet Switching?
jiya bhatia
- Jan 26th, 2010
Circuit switching is a transmission technique which is connection oriented. Connection has to be established before the actual data transmission takes place. While packet switching is connection less. The data is transmitted in the form packets one after other.
