cmos pnp

Has anyone used or have any papers/info on a lateral PNP in TSMC 0.18 or 0.25u? Optimum layout, models? What is the realistcly achievable beta?
 

pnp all cmos process

You can get this model from TSMC directly

OK, I'll try, but I can't see lateral PNP in their standard models and libraries even for RF/mixed signal process, they only have vertical PNPs and NPNs there.
 

vertical npn lateral npn cmos process

if TSMC don't have this model. you can't use the lateral PNP
 

cmos process pnp

You cannot isolate vertical and lateral p-n-p.
Actually you get two-collector p-n-p:
one collector connected to GND (vertical p-n-p)
another collector (lateral) will be floating, but the output voltage cannot be higher than Vbe (Vec>0).
And efficiency or BN of the lateral p-n-p will be very low.
I don't know where you can use such transistor.
 

vertical pnp standard cmos

give me you email add, I can send you a sample lateral PNP for TSMC 0.18/0.25.

normally, in bandgap people use PNP .

My email is now shown in the profile. Thanks a lot! Do you also have model for it?

You can find the model in MM/RF PDK
I believe the name is VPNP

vpnp is vertical PNP.

vpnp is vertical PNP.

True, but that is the only PNP you are able to make in a cmos process.

If it has deep Nwell, then, you can make lateral NPN, not PNP,
as far as I can tell

That's right, RF/mixed signal TSMC0.18 has deep nwell, so lateral PNP can be made.
