Cascode StageCascode Stage Cascode는 CS stage와 CG stage를 cascade한(직렬로 연결한) 특정한 회로입니다. (Fig. 3.59)Common-source stage에 Vin을 인가해서 생성된 전류 신호를 common-gate stage에 인가하는 겁니다. * Cascade: 여러 증폭 단을 직렬로(위아래로) 연결하여 전압 이득을 높이는 일반적인 방식* Cascode: CS stage와 CG stage를 위로 쌓아 연결하는 특별한 casc.. 2024. 11. 13. CG Stage(Common-Gate Stage) [Razavi][Ch3] 참고: Behzad Razavi, Design of Analog CMOS Integrated Circuits, Second EditionChapter 3 - Single-Stage Amplifiers (pg. 75~82)3.5. Common-Gate StageCommon-Gate Stage이전에 살펴본 CS stage와 source follower는 input 신호를 MOSFET의 gate로 인가했습니다.그런데 common gate stage의 경우에는 source에 input 신호를 인가하고, drain에서 output을 생성합니다. MOSFET의 gate는 원하는 동작에 맞게 dc voltage로 biasing합니다. Fig. 3.48(a)의 회로를 보면, M1의 Id가 input signal sou.. 2024. 11. 5. Source Follower(CD Stage) [Razavi][Ch3] 참고: Behzad Razavi, Design of Analog CMOS Integrated Circuits, Second EditionChapter 3 - Single-Stage Amplifiers (pg. 68~75)3.4. Source FollowerSource Follower앞서 알아본 CS stage의 voltage gain은 –gm*(load impedance)였습니다. (gm: Vin을 인가하는 MOSFET의 gm)그래서 높은 voltage gain을 얻으려면 load impedance가 커야 합니다. 만약 low impedance load가 달려 있다면, amplifier 뒤에 buffer를 붙여 gain의 손실을 막아야 합니다. 이때 voltage buffer 역할을 할 수 있는 게 “c.. 2024. 11. 5.
