UNIT-I INTEGRATED CIRCUITS 1.1 CLASSIFICATION OF IC’S: Integrated Circuitis a miniature, low cost electronic circuit consisting of active and passive components that are irreparably joined together on a single crystal chip of silicon. CLASSIFICATION: 1.1.1 Based on mode of operation a. Digital IC’s b. Linear IC’s Digital IC’s: Digital IC’s are complete functioning logic networks that are equivalents of basic transistor logic circuits. Ex:- gates ,counters, multiplexers, demultiplexers, shift registers. Linear IC’s: Linear IC’s are equivalents of discrete transistor networks, such as amplifiers, filters, frequency multipliers, and modulators that often require additional external components for satisfactory operation 1.1.2. Based on fabrication a. Monolithic IC’s b. Hybrid IC’s a. Monolithic IC’s : In monolithic ICs all components (active and passive) are formed simultaneously by a diffusion process. Then a metallization process is used in interconnecting these components to form the desired circuit. b. Hybrid IC’s: .In hybrid ICs, passive components (such as resistors and capacitors) and the interconnections between them are formed on an insulating substrate. The substrate is used as a chassis for the integrated components. Active components such as transistors and diodes as wellas monolithic integrated circuits, are then connected to form a complete circuit. 1.1.3. Based on number of components integrated on IC’s a. SSI <10 components b. MSI <100 components c. LSI >100 components d. VLSI >1000 components 1.2. CHIP SIZE AND CIRCUIT COMPLEXITY:
