OPERATIONAL AMPLIFIER - an amplifier that has very high gain, very high
input impedance, and very low output impedance. An operational amplifier is
made from three stages:
High-gain voltage amplifier.
the way operational amplifiers are usually used.
This means that degenerative feedback is used to lower the gain and increase
the stability of the operational amplifier.
INVERTING CONFIGURATION a way an operational amplifier circuit can be
NONINVERTING CONFIGURATION a way an operational amplifier circuit
can be connected.
