Chapter#7: Integrated Circuit and Technologies

All exercise Short Questions Integrated Circuit and Technologies of Digital Electronics book for BS/MSc Physics students.

Q.1 List three types of IC technologies and name the two that are the most widely used.

Q.2 What does the term hex inverter mean? What does quad 2-input NAND mean?

Q.3 A certain gate has a propagation delay of 5ns and I_CCH=1mA I_CCL=2.5mA With a DC supply voltage of 5V. Determine the speed-power product.

Q.4 Determine the HIGH-level and LOW-level noise margins for 5V CMOS and for 5V TTL.

Q.5 A certain gate draws 2µA when its output is HIGH and 3.6µA when its output is LOW. What is its average power dissipation if Vcc is 5V and the gate is operated on a 50% duty cycle?

Q.6 Is it better to have a lower value of noise margin or a higher value?

Q.7 How does excessive loading effect the noise margin of a  gate?

Q.8 Why must CMOS devices be handled with care?

Q.9 In term of switching action; what do the on and off states of a BJT represent?

Q.10 In what output state does a TTL circuit sink current form a load?
