Pinch off saturation

WebApr 13, 2024 · MOSFET at Saturation or Pinch-off Operating Region. If you increase the gate voltage, that positive voltage will attract electrons in the substrate up to the area between the source and drain, an area called the channel region, this time a physical region. As the electrons gather in the channel, the depletion region expands and eventually there ... Webwhere Vp is the pinch-off voltage and IDSS is the saturation current. This current (IDSS) is defined as the value of the current ID when VGS = 0, and this feature is often used to obtain a constant value current source (IDSS). This equation at the ID and VGS plane represent a parable displaced in Vp.
