Hi,
I've searched through here and on google but haven't found anything about this.
Typically, latchup is illustrated with nmos and pmos. The SCR is drawn based on those two devices. Is that to say that if the pmos was a p-diode or the nmos was replaced by an n-diode, there would be no latchup concerns? The question comes from some tests I've put together:
I can generate LU errors with nmos and pmos but if either of the nmos or pmos is replaced with a diode, LU errors desappear. Confusing because there's still a thyristor whether we have nmos/pmos combination or nmos/p-diode or pmos/ndiode combinations.
An input would be appreciated.
Thanks
