| From: | To: |
Gate To Drain Potential is defined as the voltage across the gate and the drain junction of the MOSFETs. It is a crucial parameter in MOSFET operation and circuit analysis.
The calculator uses the Gate To Drain Potential formula:
Where:
Explanation: This formula calculates the voltage difference between the gate and drain terminals based on the gate-to-channel voltage and gate-to-source potential.
Details: Accurate calculation of gate to drain potential is essential for MOSFET circuit design, analysis of switching characteristics, and ensuring proper device operation within safe voltage limits.
Tips: Enter Gate to Channel Voltage (Vgc) and Gate to Source Potential (Vgs) in volts. The calculator will compute the Gate to Drain Potential (Vgd) using the formula Vgd = 2×Vgc - Vgs.
