2022年4月13日 · Double letters (cc) refer to power supply voltages. For example, Vee refers to the "emitter" voltage. In CMOS logic, Vss refers to the "source" voltage, and Vdd is the "drain" voltage. Single letters refer to the voltage relative to ground; for example, Vc is the "collector" voltage relative to ground.

2024年2月18日 · Vss 源极电源电压, 在 CMOS 电路中指负电源, 在单电源时指零伏或接地. Vee 发射极电源电压, Emitter Voltage, 一般用于 ECL 电路的负电源电压. Vbb 基极电源电压, 用于双极晶体管的共基电路.DSP交流网 DSP学习第一论坛 DSP技术应用与推广平台 DSP开发服务平台

Given a desired emitter current IE, what values of bias resistors are required, RB, RE, etc? The simplest biasing applies a base-bias resistor between the base and a base battery VBB. It is convenient to use the existing VCC supply instead of a new bias supply.

2023年9月23日 · Vb is the convention to state the voltage at base, compared to your 0V reference, which may or may not be emitter voltage Ve. Vbe is the convention to state the voltage difference between base and emitter, so Vbe = Vb - Ve. If your emitter has 10V, your base voltage Vb should be at 10.7V, which still means Vbe is 0.7V.

2012年6月10日 · Vbb is the collector voltage as well as the voltage to bias the base. Calling it Vbb is somewhat confusing. Vin is the AC signal voltage, which is independent of Vbb. Certainly the common collector (emitter follower) configuration can operate in the active mode region.

2004年9月26日 · Vcc is the collector supply; Vbb is the base supply; Vee is the emitter supply. You usually only see Vcc as Vbb is usually derived from Vcc via voltage divider bias and Vee from a ground connection, although plenty of circuits do use a negative Vee supply.

2024年10月15日 · Vbb 基极电源电压, 用于双极晶体管的共基电路。 一般Vcc指正向的电源电压，Vdd指负向电源电压 在三极管中，VCC是集电极C的对地电压，而VBB是基极B的对地电压。

2010年4月22日 · Vcc = Collector supply voltage, Vee = Emitter supply, Vbb= Base supply voltage, Vdd = Drain supply, Vss = source supply. Whenever the supply to a Transistor (or TTL IC circuit) is connected between the collector and ground it is a standard to notify it as Vcc.

2021年6月21日 · 三极管基极电源电压Vbb为什么要写两个b？ 瞎答一波，Vbb是直流电压， 静态工作点 电压；信号vin交流从基级输入，实际上基级电压是直流电压和输入 交流分量 的合成。 所以Vbb不能完全代表 基级电压。 知乎，中文互联网高质量的问答社区和创作者聚集的原创内容平台，于 2011 年 1 月正式上线，以「让人们更好的分享知识、经验和见解，找到自己的解答」为品牌使命。 知乎凭借认真、专业、友善的社区氛围、独特的产品机制以及结构化和易获得的优质 …

2023年11月3日 · Vbb是指三极管在静态偏置情况下，基极对地的直流电位。 调节Vbb使三极管产生合适的集电极电流。 Rb是共射极基本放大器的基极偏置电阻，由Rb提供基极偏置电流。 改变Rb的大小，可使集电极电流随之变化。 Vcc是提供给放大电路工作所需的电源电压。
