Question

 We know that body effect deteriorates the behavior
of NMOS logic gates with depletion-mode loads.
Assume that the depletion-mode load device has
VT O = −1 V and is operating in an inverter circuit with VDD = 2.5 V. What is the largest value
of the body-effect parameter γ that still will allow
VO H = VDD? Assume 2φF = 0.6 V.
