In the first case, when VI is at VDD
(see Figure 3a), QN is on since the
gate is biased at VDD while the source
is still at ground. QP is off. This causes
the output (VO) to be nearly zero (typ-
ically less than 10 mV). But the current
through the two devices is nearly zero
because there is no direct path from
VDD to ground.
Enhancement In the second case, when VI is at zero
volts (see Figure 3b), QN is off since
the gate is now at the same potential
as the source; Q r is on. This causes
the output (Vo) to be almost equal to
VDD (typically less than 10 mV below
VDD). However, the current through
the two devices is still nearly zero be-
cause there is still no direct path from
VDD to ground.
From the above, we conclude that the
basic CMOS logic inverter behaves as
an "ideal" logic element; the output
voltage is almost equal to zero volts

tion is almost zero. Stated another
