2009年10月14日 · For MOSFET circuits, the three common suppies are Vdd, Vss, and Vgg for the drain, sourse and gate supply voltages. The same remarks regarding polarity apply here. The strict meaning of these has been lost among a growing number of people, and hence you will often see Vcc used as the positive supply in CMOS circuits and see Vdd in BJT circuits.

2004年4月16日 · Vcc, Vdd, etc Here's the info about Vcc, etc.: BJT FET : these are the two instances where these terms are used. Vcc Vdd = Positive Vee Vss = Negative/Ground You can access this information from: **broken link removed** There is so much here, it could take months to go through, easily. Chung Lee

2011年6月30日 · Hi everyone i am new to electronics and i would like to know wha t do the following mean Vcc, Vdd, Vss, Vs. Thx for all ur answers.

2018年1月31日 · So Vdd is the supply voltage associated with the drain node of an NFET circuit and Vss is the supply voltage associated with the source node of an NFET circuit. Not everything follows this convention and you need to learn to interpret things in terms of the schematic you are working with. Vs, in particular, is a common notation for a signal source.

2014年12月23日 · Generally a voltage pin with double letters (Vdd, Vss, Vcc and the like) mean a power rail. A single letter (Va, Vo, Vb) mean some signal voltage between the power rails. Vdd generally means the Drain supply on CMOS circuits (positive power). Vss generally means the Source supply on CMOS circuits (ground common).

2015年12月10日 · This is done to improve the dynamic current distribution inside the chip. You simply MUST connect all VDD and VSS pairs to your power supply and decouple each pair with 0.1 uF ceramic capacitor placing it as close as possible to the VDD/VSS pin pair.

2020年5月7日 · Some use Vss or Vcc, Vdd or Vee , ie: transistor's, fet's Gnd or 0V, usually refers to the measurement reference Node, I only use Earth for an actual connection to physical Earth On your switch diagram I would use Vin, Vo1, Vo2.

2010年11月14日 · If the IC has a dual-rail supply (eg: Vcc/Vdd, GND, and Vee/Vss) then you need at least two caps; one from GND to Vcc/Vdd and one from GND to Vee/Vss. All logic IC's (74xx, 4000 series) require one 0.1uF/100nF cap across the Vcc/Vdd/GND supply right at the IC itself. MCU's/uC's also require at least one bypass cap.
