What is drain current in MOSFET?

The drain current below threshold voltage is defined as the subthreshold current and varies exponentially with Vgs. The reciprocal of the slope of the log(Ids) vs. Vgs characteristic is defined as the subthreshold slope, S, and is one of the most critical performance metrics for MOSFETs in logic applications.

Which way does current flow in a PMOS?

In an NMOS electrons are the charge carriers. So electrons travel from Source to Drain (meaning the current goes from Drain > Source.) In a PMOS holes are the charge carriers1. So holes travel from Source to Drain.

What is Drain current in the saturation region of PMOS transistor when Vov is given?
The Drain current in the saturation region of PMOS transistor when Vov is given, drain current first increases linearly with the applied drain-to-source voltage, but then reaches a maximum value. A depletion layer located at the drain end of the gate accommodates the additional drain-to-source voltage. This behavior is referred to as drain current saturation and is represented as Ids=1/2*k'n*AV*(Vov)^2 or Saturation drain current=1/2*Process transconductance parameter*Aspect Ratio*(Effective voltage or overdrive voltage)^2. Process transconductance parameter is the product of mobility of electrons in channel and oxide capacitance, Aspect Ratio is the ratio of the .width of the channel to the length of the channel and Effective voltage or overdrive voltage is excess of voltage across oxide over thermal voltage is termed.
