UNIT-I CIRCUIT CONFIGURATION FOR LINEAR ICs 2 marks questions 1.Mention the advantages of merged circuits. *Miniaturisation and hence increased equipment density. *Cost reduction delinquent to batch impact. *Increased system reliability due to the occlusion of soldered joints. *Improved functional performance. *Matched devices. *Increased operating speeds. *Reduction in power consumption. 2.Write down the several(a) processes used to fabricate IC’s using silicon planar technology. *Silicon wafer preparation. * Epitaxial yield *Oxidation. *Photolithography. *Diffusion. *Ion implantation. *Isolation. *Met in allisation. *Assembly processing and packaging. 3.What is the purpose of oxidation? *SiO2 is an extremely austere protective coat and is unaffected by almost all reagents. *By selective etch of SiO2, diffusion of impurities through carefully defined windows advise be cultured to fabricate various components. 4.Why aluminium is preferr ed for metallization? *It is a honourable conductor. *it is easy to alluviation aluminium films using vacuum deposition. *It makes strong mechanical bonds with silicon. *It forms a low resistance contact. 5. What are the hot IC packages for sale? Metal can package. Dual-in-line package. Ceramic apartment package. 6.

Define an available amplifier. An operational amplifier is a direct-coupled, high fall upon amplifier consisting of one or more differential amplifier. By by rights selecting the external components, it can be used to perform a course of numeral operations. 7.Mention the characterist ics of an ideal op-amp. * Open loop voltage! defecate is infinity. * foreplay impedance is infinity. *Output impedance is zero. *Bandwidth is infinity. *Zero offset. 8.What happens when the parkland destruction of V+ and V- sources is not grounded? If the common point of the cardinal supplies is not grounded, twice the supply voltage will experience use and it may damage the op-amp. 9.Define input offset voltage.
