EC6404   LINEAR INTEGRATED CIRCUITS  QUESTION BANK

UNIT-I 2-marks

1. Define an Integrated circuit.
An integrated circuit(IC) is a miniature ,low cost electronic circuit consisting of active and passive components fabricated together on a single crystal of silicon.The active components are transistors and diodes and passive components are resistors and capacitors.

2. Mention the advantages of integrated circuits over discrete components. (May 2010) *Miniaturisation and hence increased equipment density.
*Cost reduction due to batch processing.
*Increased system reliability due to the elimination of soldered joints.

*Improved functional performance.
*Matched devices. *Increased operating speeds. *Reduction in power consumption.

3. Define sheet resistance.(may 2010)
Sheet resistance is defined as the resistance in ohms /square offered by the diffused area.

4. What is the use of buried n+ layer in monolithic IC transistor?(MAY 2010)
The buried n+ layer provides a low resistance path in the active collector region for the flow of current

5. What are the two common methods for obtaining integrated capacitors? (may 2010) • Monolithic junction capacitor
• Thin-flim capacitor

6.What are the basic processes involved in fabricating ICs using planar technology? 1.Silicon wafer (substrate) preparation
2.Epitaxial growth
3.Oxidation

4.Photolithography
5.Diffusion
6.Ion implantation
7.Isolation technique 8.Metallization
9.Assembly processing & packaging

7. What is active load? Where it is used and why? (MAY/JUNE 2010 )
The active load realized using current source in place of the passive load in the collector arm of differencial amplifier makes it possible to achieve high voltage gain without requiring large power supply voltage.
