What is Vdd in electronics?
Understand the Problem
The question is asking about the meaning of 'Vdd' in electronics. This term typically refers to the supply voltage in digital circuits, particularly the positive voltage supplied to the drain of a transistor in CMOS technology. Understanding Vdd is important for comprehending how electronic circuits operate, especially in relation to power supply and signal levels.
Answer
The positive supply voltage for FET circuits.
VDD is the positive supply voltage for circuits using Field-Effect Transistors (FET).
Answer for screen readers
VDD is the positive supply voltage for circuits using Field-Effect Transistors (FET).
More Information
VDD stands for Voltage at Drain and is typically used in the context of MOSFETs where it denotes the voltage applied to the drain terminal. It plays a critical role in determining the operating point and behavior of MOSFET-based circuits.
Tips
VDD is often confused with VCC, which is the supply voltage for Bipolar Junction Transistors (BJTs). Always remember that VDD refers specifically to Field-Effect Transistors.
