This set of Linear Integrated Circuit Multiple Choice Questions & Answers (MCQs) focuses on “IC Chip Size and Circuit Complexity”.
1. How many gates per chip are used in first generation Integrated Circuits? a) 3-30 b) 30-300 c) 300-3000 d) More than 3000
View Answer
Answer: a
Explanation: The first generation ICs belongs to small scale integration, which consists of 3-30 gates per chip (approximately).
2. Find the chip area for a Medium Scale Integration IC?
a) 8 mm3
b) 4 mm2
c) 64 mm3
d) 16 mm2
View Answer
Answer: d
Explanation: The approximate length and breadth of Medium Scale Integration would be 4 mm. Therefore, its area is given as = length × breadth = 4mm × 4mm = 16mm2.
3. The number of transistors used in Very Large Scale Integration is
a) 107 transistors/chip
b) 106 – 107 transistors/chip
c) 203 – 105 transistors/chip
d) 102 – 203 transistors/chip
View Answer
Answer: c
Explanation: Very Large Scale Integration (VLSI) ICs are fabricated using more than 3000 gates/chip, which is equivalent to 20,000 – 1,00,00,00 transistors/chip.

4. What type of integration is chosen to fabricate Integrated Circuits like Counters, multiplexers and Adders? a) Small Scale Integration (SSI) b) Medium Scale Integration (MSI) c) Large Scale Integration (LSI) d) Very Large Scale Integration (VLSI)
View Answer
Answer: b
Explanation: Fabrication of ICs like counter, multiplexers and Adders requires 30-300 gates per chip. Therefore, Medium Scale Integration is best suitable.
5. Determine the chip area for Large Scale Integration ICs.
a) 1,00,000 mil2
b) 10,000 mil2
c) 1,60,000 mil2
d) 16,000 mil2
View Answer
Answer: c
Explanation: The chip area for a Large Scale Integration IC is 1 cm2.
=> Area of LSI = 10mm × 10mm = 1cm × 1 cm = 1cm2.
=> 1,60,000mil2 (1cm=400mil).
