Why are two diode connected transistors used in inverter based Power on reset?
Reference: Low cost low power POR circuit for low voltage sensing using adaptive bulk biasing

Hi,

do you want us to do an internet search? ... to maybe find the circuit you are talking about?

Why no link or a schematic?

Hi,

Maybe to create a voltage drop.
 

Seems like a crappy scheme to me, having designed many
PORs into production ICs. The first inverter will make the
second stage poorly driven and draw current full time, with
its value pretty variable.
