Contents • Complex number calculation • Complex Exponential • Linear system • Phasor • RC-circuit • Defferentiator • Integrator • Bode plot • Negative Resistance Converter • supplying source into Op Amp circuit
Complex numbercalculation • Complex Exponential • (단위시간당 도는 정도) • If w=const(정해졌다면) (rcoswt, rsinwt)=rcoswt+jrsinwt →
Complex numbercalculation • Linear system 크기, 위상만 바뀐다.
Complex numbercalculation • Phasor
Complex numbercalculation • Phasor에서 time function 구하기
Complex numbercalculation Re{입력의 phasor전달함수 } =>출력
Complex numbercalculation • RC-circuit • ∠0
Complex numbercalculation • Differentiator ( 미분기 )
Complex numbercalculation • Differentiator phasor • ∠0
Complex numbercalculation • |H| • H wRC w wRC w
Complex numbercalculation • 실제 쓰이는 미분기 회로 0.707 미분기 반전증폭기 High pass filter
Complex numbercalculation • Integrator • 반전 증폭기이기 때문에 만큼 shift 0.707
Bode plot 기울기=20dB/dec W가 10배 늘어나면 20씩 떨어진다. 3dB
Bode plot • 인 를 이라하고 상수
supplying source into Op Amp circuit + + Bypass capacitor Decoupling Capacitor = + Capacitor는 고주파에서 short 상태 이므로 노이즈를 제거 할 수 있다.
supplying source into Op Amp circuit • Op Amp에 흐르는 전류 • Op Amp가 부하에게 전류 공급. • Op Amp가 부하로 부터 전류를 Sink. • 저전력 Op Amp는 Op Amp
