[理工] [電子]-請問一些簡單的觀念題
ex1 Choose the single configuration that is best suitable for implementation of
CMOS static memery address decoder?
A. Psuedo NMOS NOR logic B. Pseudo NMOS NAND logic
C. CMOS NOR logic D. CMOS NAND logic
答案是A 請問為什麼呢!? 不知道怎麼去分辨這些閘的差別 請懂得人解釋一下 謝謝~
ex2 Choose the single incorrect statement baout folded-cascode differential
,as compared with cascode differential amplifier ?
A. It achieves the purpose of level shifting
B. It achieves the purpose of increasing input common-mode range
C. It is often better suited for low-voltage application
D. It is often much better in term of frequency response
答案是D 不知道 為什麼 = = 只知道B是對的 其他三個選項不知道他在敘述什麼
何謂 level shifting 呢? low - voltage application 又是指什麼意思
請各位幫忙解惑一下 感恩囉~
