Conductance of a channel is typically defined as the ratio of the current passing through the channel to the voltage across it. In MOSFETs, it represents how easily current flows through the channel when a voltage is applied.
The calculator uses the formula:
Where:
Explanation: The conductance is simply the reciprocal of the linear resistance, following Ohm's Law principles.
Details: Accurate conductance calculation is crucial for analyzing MOSFET performance, designing electronic circuits, and understanding current flow characteristics in semiconductor devices.
Tips: Enter the linear resistance value in Ohms. The value must be greater than zero to obtain a valid conductance calculation.
Q1: What is the relationship between conductance and resistance?
A: Conductance is the reciprocal of resistance. Higher resistance means lower conductance, and vice versa.
Q2: What are typical conductance values for MOSFETs?
A: Conductance values vary widely depending on MOSFET type and operating conditions, typically ranging from microsiemens to several siemens.
Q3: How does temperature affect conductance?
A: In semiconductors, conductance typically increases with temperature due to increased carrier mobility, unlike metals where it decreases.
Q4: What is the difference between conductance and transconductance?
A: Conductance refers to DC current flow, while transconductance refers to the change in output current relative to input voltage changes.
Q5: Why is conductance important in circuit design?
A: Conductance helps designers understand current carrying capacity, power dissipation, and overall performance of MOSFET devices in circuits.
