含义:表示“正电源电压”(Positive Supply Voltage),在某些情况下与 VCC 相同。 应用:在 CMOS 逻辑电路中,VDD 常用于表示供电电压,通常是正电源。 3. VSS 含义:表示“负电源电压”或“接地”(Negative Supply Voltage/Ground),在某些情况下与 GND 相同。 应用:在 CMOS 逻辑电路中,VSS 通常指代接地或负电源。

they were NPN because for some reasons I'm not going to get into, NPN were faster. Back then it made sense to someone that the positive supply voltage would be called Vcc where the "c" stands for collector. Sometimes (but less commonly) the negative supply...

VSS (Voltage Source Supply)在电路中主要指的是源极到源极的电压或特定于某些集成电路(如CMOS)的接地电压。它不是传统意义上的电源电压,而是作为源级引脚之间或源级与地之间的电压参考点。VSS在电路中为电流提供回流的路径,确保电路中的电流能够正常循环,从而使电路能够稳定工作。
For digital circuits, VCC is the power supply voltage of the circuit, VDD is the working voltage of the chip (usually Vcc>Vdd), and VSS is the ground point. For example, for ARM single-chip microcomputer, its power supply voltage VCC is generally 5V, which is generally converted into the...
Vcc Vdd Positive supply voltage Vee Vss Negative supply, ground Apparently this terminology originated in some way from the terminals of each type of transistor, and their common connections in logic circuits (i.e., Vcc is often applied to BJT collectors, Vee to BJT emitters, Vdd to FET drai...
I am in this article XDP™ XDPS2222: PFC + hybrid flyback combo IC For 240 W USB PD form factor reference design, I saw the part about VCC voltage regulation circuit, and I was curious why the MOSFET here chose the structure of Depletion MOSFET instead of Enhancement MO...

“CC” stands for “common collector”, since all the BJT collectors were tied to the same supply voltage. We all adopted the double “CC” notation for MOSFET’s too, for common supplies and grounds. 另一个人在相关问题的回答 Ivan Batinic Related What is the difference between VCC, VDD...
