Bandgap design
Aug 16th, 2021, 10:38am
 
Dear All-
I haven't seen any bandgap design with npn devices, through they are available in the kit? At least in TSMC i have seen both npn and pnp but every one (including me) designed with pnp itself? Their Beta values are very similar even. Can any one please share your experience or please point me a reference.

Thanks,
Raj.

NPN needs deep-nwell process usually is expensive. so from cost point of view it is not used very often. Smiley
