Expert Solution
Step 1

"Since you have posted a question with two question we will solve only one question for you .To get remaining part solved please repost the complete question and mention the another part to be solved."

An Op-Amp (operational amplifier) is an integrated electronic circuit that is used to amplify weak electrical signals. An operational amplifier has one output and two inputs. Its basic role is to amplify the voltage difference between the two input signals. Therefore, Op-Amp's are extensively used in filtering and signal conditioning or performing mathematical operations such as integration, differentiation, multiplication, addition, and subtract.

CHARACTERISTICS OF OPAMP:

  • Open-loop gain→ Very high
  • Input resistance→ Very high
  • Output resistance→ Very low
  • Bandwidth→ Very high
  • Offset voltage→ Very low
  • common-mode rejection ratio(CMRR)→Very high
  • Slew rate→ Very high
