[SOLVED] How to implemente a bridge of four diodes between VDD and VSS in cmos tech?

Hi,

How to design a bridge of 4 diodes in cmos process (nwell psub)?
I simulate the structures of bridge rectifier ( that i find in papers) but it doesn't work.

Thanks,

Look on baseline restorer circuit implementation in cmos (popular in radiation detectors front-ends electronic). There are development from discrete diode bridge structures.

but it doesn't work

Means what? Unable to implement suitable diodes in CMOS process? How about diode connected MOS transistors?

In junction-isolated CMOS you need to bear in mind that a
"simple diode" is seldom just that. The models may be.

One solution is here:

Which article? What's its title, please?

 

[Tahirmis_ic]

, it is a thread on researchgate, there is one solution of implementing back_to_back_silicon_diodes_in_the_negative_feeback_path_of_an_op-amp_in_CMOS, you can adjust it to the bridge

Ok, this link works (the previous didn't), thank you!
