Question

How are components array available in IC form?

(a) Array of silicon wafer

(b) Group of isolated transistor, diodes and resistor

(c) Array of individual stages of differential and cascade amplifier

(d) Group of gates logic circuits arranged in array format

The question was posed to me during an interview.

The above asked question is from Integrated Circuit Package Type, Pin Configuration and Temperature Range topic in portion Operational Amplifier Characteristics of Linear Integrated Circuits

Answer 1

In IC manufacturing, component arrays are typically available as a group of isolated transistors, diodes, and resistors fabricated together on the silicon substrate. This approach allows for:

Matched pairs - for differential circuits

Compact layout - saves chip area

Better performance - similar processing conditions

Answer: (b) Group of isolated transistor, diodes and resistor
