Document Summary
1. 5. 1 calculation of output-offset voltages due to input- 1. 5. 2 calculation of output-offset voltages due to input- Aims: operational amplifiers are briefly looked at, with the golden rules used for circuit analysis given, additionally some common and very useful circuits are presented, finally the effect of d. c. imperfections of real op amps are looked at. What is missing: the internal circuitry of real op amps will be presented, but only after the small signal analysis of transistor circuits has been presented. After section 2, the internal circuitry of an op amp should mean something to you: the behaviour of the op amp as the frequency of the input signal is varied. As will become apparent, the behaviour of op amps as a function of frequency is a direct consequence of. 1. 1 the ideal op-amp basic properties: direct coupled, i. e. , not capacitively, high gain, basic linear (analogue) integrated circuit, differential input + and non inverting or inverting input, single ended output, usually.
