Note: Depletion mode refers to the channel being inverted at Vgs = 0, similar to a typical JFET, you use the gate to pull the device out of conduction. Pseudo-NMOS; A grounded PMOS device presents an even better load. It is better than depletion NMOS because there is no body effect (its V SB is constant and equal to 0). Also, the PMOS device is driven by a V GS = -V DD, resulting in a higher load-current level than a similarly sized depletion-NMOS device.
