Subthreshold conduction refers to the phenomenon where a transistor allows current to flow even when the gate-to-source voltage is below the threshold voltage, primarily due to the exponential relationship between current and voltage in this region. This behavior is crucial for low-power electronic applications, as it affects the leakage current and power efficiency of integrated circuits.

Transistor current flow

Gate-to-Source Voltage (Vgs) is a critical parameter in field-effect transistors (FETs) that controls the conductivity of the channel between the source and drain terminals. By adjusting the Vgs, one can modulate the current flow through the device, making it essential for switching and amplification applications in electronic circuits.

gate-to-source voltage

Threshold voltage is the minimum gate-to-source voltage differential that is required to create a conducting path between the source and drain terminals of a field-effect transistor (FET). It is a critical parameter that influences the switching characteristics and power consumption of semiconductor devices.

low-power electronic applications

Leakage current refers to the unwanted flow of electrical current that occurs in an insulating material or device, even when it is supposed to be in a non-conducting state. This phenomenon can lead to power loss, reduced efficiency, and potential damage to electronic components if not properly managed or minimized.

leakage current

Power efficiency refers to the ratio of useful power output to the total power input, maximizing performance while minimizing energy waste. It is crucial in reducing operational costs and environmental impact across various technologies and systems.

power efficiency

Integrated circuits (ICs) are miniaturized electronic circuits consisting of semiconductor devices and passive components that are fabricated onto a single piece of semiconductor material, usually silicon. They revolutionized electronics by enabling complex functionalities in small form factors, paving the way for modern computing and communications technologies.
