What is threshhold voltage?

Threshold voltage is the minimum voltage required to activate a transistor or other electronic component and allow current to flow through it. It is the point at which the device transitions from an off state to an on state. In transistors, the threshold voltage is the voltage at which the transistor's gate becomes sufficiently positive with respect to its source to turn it on. This voltage is usually determined during the manufacturing process and is dependent on the specific characteristics of the device. The threshold voltage is important as it determines the amount of electrical current that will be needed to activate the device and can affect its performance and reliability. It is also an important factor in determining the power consumption of electronic circuits.
