What does VSS and VDD mean?
When an electronic circuit or IC is made using Filed Effect Transistors the supply voltage pins are denoted as Vdd and Vss. Vdd refers that the supply voltage pin is connected to the drain of the transistor. Vss refers that the supply voltage pin is connected to the source of the transistor.
What is VSS and VCC?
VCC (Voltage Common Collector) is the higher voltage with respect to GND (ground). VCC is the power input of a device. It may be positive or negative with respect to GND. When the only positive power supply is used then VSS (Voltage Source Supply) means ground or zero.
Is VSS a ground?
VSS is normally the system ground and the term VSS is often used interchangeably with the term GND.
What does B stand for in electricity?
Circuit Breaker

Why is ground called VSS?
They are all supply voltages. Vcc = Collector supply voltage, Vee = Emitter supply, Vdd = Drain supply, Vss = source supply.
Does VDD mean ground?
No, VDD is the positive power voltage and VSS is the 0 V (or “ground” voltage). D and S refer to “drain” and “source”, respectively. In a single supply circuit, VSS is usually the ground.
What is VSS voltage?
Nowadays it is always used Vdd and Vss to refer to the positive and negative voltage respectively. Vdd is normally was used to be 5V but nowadays is 3.3V or even lower 1.8V or 1.2V. Vss is referred to be zero volts.
What is VDD and GND?
VDD is the DC Power supply connected to Drain Terminal of any FET circuit. The positive will be connected to the Drain and negative/GND will be the Source.
What does R stand for in circuits?
Resistance measured in ohms, symbolized by the letter “R”.
What does R mean in electricity?
resistance
where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms.
What VSS means?
A voluntary separation scheme (‘VSS’) is a scheme/ offer where an employer invites and offers the employee to resign voluntarily without the implications of a retrenchment while still receiving fair compensation from it.
