                           Electronic Circuits Design
                                                                 Date: June 12, 2012.
1. 다음 Attenuator 회로를 E24 계열 저항으로 바꾸어라. (20) E24 계열 저항의
   선호수는 아래와 같다.
   10, 11, 12, 13, 15, 16, 18, 20, 22, 24, 27, 30, 33, 36, 39, 43, 47, 51, 56, 62, 68,
   75, 82, 91




                          R1 = 93 [Ω], R2 = 370 [Ω]


     AV = 36 [dB]
2.                가 되는 반전 증폭기를 Op-Amp로 설계하라. 구체적인 저항

                           dB = 20 log10 AV
     값을 명시하시오. (40) [Hint]




         1)   E24 계열 저항으로 설계하시오. (20)



         2)   위의 핀 배치도를 이용해 반전 증폭기의 결선구조를 제시하시오.
              증폭기에 사용한 저항, 커패시터, 입력원인 Function Generator, 부
              하인 Oscilloscope도 표시하라. (20)
3. 1 [kHz]에서 사용할 커패시터의 실제 용량(C와 R)을 LCR Meter로 측정하
 고자 한다. 측정 방법을 순서와 절차에 따라 쓰시오. (20)




4. CE Amplifier의 대역폭을 찾는 절차를 설명하시오. (20)
