과기대 와서 김성권교수님을 만난건 천운이라고 생각한다. 

op-Amp부터 반도체, 전자회로1,2 응용전자회로 , 양자역학까지 너무 재밌게 배웠다. 

이 어려운 전자공학 과목들을 완전히 이해는 못해도 즐기면서 배울 수 있었던건 교수님 덕분이라고 생각한다.

 

1. Operation with a Differential input Voltage

2. Large Signal Operation



3. Small Signal Operation - Differential Gain

 - Differential Half-Gain

4. The Differential Amplifier with Current-Source Loads



5. Cascode Differential Amplifier 

 - Effect of RD Mismatch

 - Effect of gm Mismatch



6. DC Offset

7. The Differential Amplifier with a Current-Mirror Load

8. The Current-Mirror-Loaded MOS Differential Pair
