We therefore call this load the “Pseudo NMOS Load”, since it is the load used in Pseudo NMOS logic. But, keep in mind that the pseudo NMOS load is made from a PMOS device (this can The Pseudo-nMOS Full Adder cell is worked by Pseudo-nMOS logic or rationed logic. The CMOS pull up network is substituted by a single pMOS transistor with its gate grounded. The pMOS is always ‘on’ because it is not driven by signals. Vdd is the effective gate voltage seen by the pMOS transistor. When the nMOS is turned ‘on’, static power will be drawn …
Then, if you take the value of RDSon R D S o n in the datasheet (it gives only the maximum, 5 Ohm) and knowing that the values are for Vgs = 10 V and Ids = 500 mA, you can put it in the formula of IDS (lin) and obtain Kn.
