  1. 전자 회로 1Lecture 7 (MOSFET-II) 2009. 05. 임한조 아주대학교 전자공학부 hanjolim@ajou.ac.kr 이 강의 노트는 전자공학부 곽노준 교수께서 08.03에 작성한 것으로 노트제공에 감사드림.

  2. Review (operation mode) NMOS PMOS Nojun Kwak

  3. MOSFET at DC Nojun Kwak

  4. Nojun Kwak

  5. Nojun Kwak

  6. CMOS inverter Nojun Kwak

  7. Large signal operation Nojun Kwak

  8. Saturation mode: Nojun Kwak

  9. Biasing in MOS Amp. • Amp 주로 Saturation 영역을 이용함 • Cf) Inverter: Cutoff + Triode • Solution: Degeneration Resistance in the Source 온도의 함수 소자마다 다름 : negative feedback Nojun Kwak

  10. Degeneration Resistance in the Source Large Rin Nojun Kwak

  11. Drain-to-Gate Feedback Resistance Limited output voltage swing Nojun Kwak

  12. Constant Current Source Current mirror R을 조정함으로써 IREF를 적절히 조절 Nojun Kwak

  13. Small signal operation • DC bias point (Q-point) • Total Current iD 소신호 모델 = 매우 작음 Nojun Kwak

  14. Transconductance Voltage Gain (전압이득) Transcoductance & Voltage gain Nojun Kwak

  15. Small signal models (hybrid-π & T) Nojun Kwak

  16. Channel-length Modulation (ro) • BJT의 Early effect모델과 비슷함 ro를 추가 • 참고: large signal model과 gm이 다름 Nojun Kwak

  17. Body effect 고려 • Source가 Body와 같은 전위가 아닐 때 사용 Nojun Kwak

  18. Summary: Small Signal model (I) Nojun Kwak

  19. Summary: Small Signal model (II) Nojun Kwak
