6.9 SUMMARY
- This chapter introduced the Operational Amplifier as a circuit element and developed a model called the ‘Ideal Operational Amplifier Model’ (IOA model) for analysing circuits containing Opamps.
- Various factors that set limits to the output voltage, output current and rate of change of output voltage in voltage amplifiers were discussed with a MOSFET amplifier taken as an example to develop the related concepts. Various causes of waveform distortion in voltage amplifiers were also examined using this MOSFET amplifier as an example. This was necessary to set the background for the study of Opamps and to understand some limitations that they suffer from in circuit applications. The role of DC power supplies in setting the output limits ...
