Electronics and Communication Engineering Interview Questions and Answers
Question - 41 : - What is op amp?
Answer - 41 : - An operational amplifier, often called an opamp , is a DC coupledhigh gain electronic voltage amplifier with differential inputs[1] and, usually, a single output. Typically the output of the opamp is controlled either by negative feedback, which largely determines the magnitude of its output voltage gain, or by positive feedback, which facilitates regenerative gain and oscillation.
