•  EE359 – your_Stevens_email_ID – HW#, e.g. “EE359-bmcnair-HW3.doc”

•  Partial answers will receive partial credit •  Answers with no work shown will receive minimal credit •  Submissions will be graded as if you used the correct textbook

(Sedra & Smith, 7th edition - not 6th, not international, etc.) •  Put pledge in submission file, not in email message •  UNPLEDGED ASSIGNMENTS WILL NOT BE GRADED –

It is an Honor System rule •  HONOR CODE VIOLATIONS WILL NOT BE TOLERATED •  ALL WORK IN THIS CLASS IS INDIVIDUAL WORK

Overview of Basic Concepts

Amplifiers •  Linear Signal

Amplification:

•  A: Amplifier gain equals the slope

•  Distortion changes waveform as in figure

•  No real life amplifier is perfectly linear, distortion due to clipping

7

Nonlinearity

•  Most amplifiers are only linear in a narrow range of operation

•  To linearize, bias the circuit with a dc voltage, labeled Q, the quiescent point.

8

Low Pass Filter (LPF) Frequency Response • Magnitude Response

OPAMP

•  Dual in Line Packaging(DIP)

OPAMP PACKAGING
