• The DC input power, heat generation and maximum thermal resistance of class A and B amplifiers are calculated, and the resulting numbers indicate that a Class A amplifier is an enormous power waster in comparison to a class B amplifier.

  We also know that the BJT power transistor has a maximum junction temperature of 155 degrees C, if the ambient temperature is 25 degrees C.

  These capacitive models enable the circuit designers to predict the operating frequency of their amplifiers using transistors. 3.

• Operation Amplifiers

  It consists of a differential amplifier that gets the difference between its two input terminals and amplifies them, and a signal driver that provides power to the differential signal to send it to its output terminal.

• Operational Amp

  Basic operation: The amplifier's differential inputs consist of an inverting input and a non-inverting input and ideally the op-amp amplifies only the difference in voltage between the two. This is called the "differential input voltage."

• Op Amps

  This offset causes an offset in the output voltage because a slight differential voltage becomes present at the input, especially at high-gain amplifiers.

• Class B Amplifier Distortion Summary

  Op-Amps are differential voltage amplifiers and try to match the levels on both of their inputs.
