Hi
i want to simulate this structure :
so i write this Net list:
but after simulation the result isn't expectation result.
this is the output:
the expected result is like this:
i try to simulate simple architecture of bulk driven like this:
so i write this net list for simulation:
this is the result after simulation:
while the expected result is like this:
so what do you think? where is my mistake in simulation and Net list?
Thanks
i want to simulate this structure :
so i write this Net list:
Code:
.param Ibias1=.3m
.param v1=.8v
.param v5=.4v
*+++++++++++++++++++++++++++++++++++++++++++++++++++++++*
VDD 1 0 DC v1
VG 2 0 DC 0
VB 5 0 DC v5
IDSS1 3 0 50U
IDSS2 7 0 50U
Iin1 33 0 Ibias1
*+++++++++++++++++++++++++++++++++++++++++++++++++++++++*
M1 4 2 1 3 P_LV_18_MM l=.2u w=3u
M2 3 2 4 5 P_LV_18_MM l=.2u w=6u
M3 6 2 1 3 P_LV_18_MM l=.2u w=3u
M4 7 2 6 5 P_LV_18_MM l=.2u w=6u
*+++++++++++++++++++++++++++++++++++++++++++++++++++++++*
RL1 7 0 1k
Rin 3 33 0
*+++++++++++++++++++++++++++++++++++++++++++++++++++++++*
.OP
.dc sweep Ibias1 0u 200u 5u
.probe i(RL1)
.probe i(Rin)
*+++++++++++++++++++++++++++++++++++++++++++++++++++++++*
.END

Code:
.param Ibias1=400u

this is the result after simulation:
while the expected result is like this:
so what do you think? where is my mistake in simulation and Net list?
