ELE-122 Linear Integrated Circuits Integrated Circuits(IC): An integrated circuit is a collection of discrete elements (resistor, capacitor, diode and transistor) created by means of a single construction process in which all elements are formed. In another word, IC is collection of electronic components or circuits on a single chip of semiconductor material. Analogue IC: An analogue IC performs amplification or linear operation on signal, so it is called Linear IC. Example: Operational amplifier IC(IC 741) Digital IC: Digital IC performs the circuit function dealing with discrete quantities i.e integer and fractional number(means bit 0 or 1). Example: All Gate IC (e.g 7400-NAND gate IC, 7404-NOT gate IC)
