form a sub-class of such systems. Opamp is an important electronic amplifier that senses a
voltage difference and amplifies it into a voltage at the output.
We introduce this important circuit element and develop a method for analysing
memoryless circuits containing Opamps in this chapter.
6.1 IDEAL AMPLIFIERS AND THEIR FEATURES
Amplificationof a signal involves sensing a signalacross a pair of terminals (if it is a voltage
signal) or through a pair of terminals (if it is a current signal) and producing an identical
copy of this signal across (or through) a second pair of terminals with only a scaling by a
real number >1 and a possible change in dimensions ...
