Calculate the current in the saturation region of a MOSFET in strong inversion

In analog CMOS design the MOSFET is usually operated in saturation where the IDS – VDS curves are close to being flat. The slight slope leads to the definition of the channel length modulation parameter. A simple calculator has been released by Signal Processing Group to allow a first order calculation of this current as starting points of a design. Please visit the SPG website and look under the “calculators” menu item.
