The test conditions for the resistive switching performance is shown in Table 5. The resistive switching times obtained with the
above TTL and CMOS gates are tabulated in Table 6. In this table t
on
= Time in microseconds from 90% to 10% V
DD
and t
off
=
Time in microseconds from 10% to 90% V
DD
. Inductive switching gives faster voltage rise times than resistive switching due to
the resonant charging of the output capacitance of the device. Voltage fall times are essentially the same.
