  18. 18. Dr. Neeraj Misra 19 Current Sink : In order to work the transistor as a current sink the transistor should be operated in linear region. Figure below shows the output characteristics of the NMOS transistor with showing the current sink region. From Figure, it can be seen that, if VDS is less than the gate overdrive voltage then the transistor work as a current sink.
  19. 19. Dr. Neeraj Misra 20 Current Sources : In order to use the MOSFET as a current source, we will have to operate it in saturation region. According to the output characteristics of the MOSFET, the current in the saturation region is constant. (See Figure below). Therefore if we operate the MOSFET in saturation region it will work as a current source. From Figure it can be seen that, if VDS is greater than the gate overdrive voltage then the drain current flowing through the device is constant. This current is called as Saturation current denoted by ISAT.
