The device that can act as a complete electronic circuit is
(a) Junction diode
(b) Integrated circuit
(c) Junction transistor
(d) Zener diode
Integrated circuits are miniature electronic circuit produced within a single crystal of a semiconductors such as silicon. They contain a million or so transistors and resistors or capacitors. They are widely used in memory circuits, micro computers, pocket calculators and electronic watches on account of their low cost and bulk, reliability into specific regions of the semiconductor crystals.
