Integrated Circuits
Course
objective:
A
linear integrated circuit is a solid-state analog device capable of operating
across a continuous range of input levels, offering theoretically infinite
operating states. These circuits are commonly used in applications such as
audio amplifiers, analog-to-digital
converters,averagingamplifiers,differentiators,DCamplifiers,integrators, multivibrators,
oscillators, audio filters, and sweep generators.
