Hi all.
I'm sweeping the linear regulator input voltage on DC from 0V to maximum expected Vin. However, as the OTA that makes part of LDO is internally supplied by the output voltage, the simulation will never turn on the OTA and it will find a very stable point of operation in 0V. it is like the dilemma of chicken and egg.
How I could force to start the OTA and calculate the minimim input voltage?
Thanks
