根據每一項給你一些提示 ※ 引述《ikju (小陽)》之銘言: : Using TSMC 0.35um process with single supply voltage : VDD=3V and load capacitance CL=5pF via HSPICE : design a differential input single-ended : output operational amplifier having : the following specifications: :  open-loop gain: 80dB large open-loop gain: 1st stage: cascode/telescope/folded cascode 2nd stage: common-source with active load : . unity-gain frequency: 10MHz for 60deg PM, BW2 = 2.5 GBW : . input common-mode range: 2V that is, 0.5V~2.5V 請參照Razavi 第九章 選擇folded cascode, rail-to-rail : . output voltage swing: 2V Vo: 0.5V~2.5V |Vgs| of both MOS: 1V : . power dissipation: 3mW total current: 1mA => I2 = 700uA~800uA 剩下的請用在folded cascode rail-to-rail : . CMRR: 70dB large L of current source : 請問有人會設計嗎 : 符合一兩個條件就可以了 : 謝謝回答 -- 不用layout這樣的OP兩天內應該可以完成 -- ╭ █◣◢█ ╮ ╭ ███◣╮ ╭═══╮ ╭═════╮ ╭═════╮ ║ ████ ╰══╯ █ ◥█╰══╯◢ ╰═╯ ◢▌ ◢╰══╯ ║ ║ ████ ◢◢◣ █◣ █ ◢█◣ █ ◢ ◢█◣ ██◣ █ ◢█◣ ˙ █◥◤█ █◤ ███◤ █◢◤ █ █ █◢█ █▌█ █ █◢◤☆  ̄ρ ║ ◥ ◤ █ ● █◥█◣ ◥█◤ █ ◤ ◥◤◥ ◥█◤ █ ◥█◤ 〈╭﹀║ New York Yankees═ ◤ ════ #40 ◤ Chien-Ming Wang═◤═══ψTheAnswer3╯ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 220.135.83.97 ※ 編輯: deathcustom 來自: 220.135.83.97 (01/08 18:00)
