Hi all,
As in the title I have two questions:
1)I have seen that when referring to some new technology of transistors it is said for example 28nm or some other length which as far as I have understood refers to gate length, is it correct?
If so why is that parameter taken into consideration since often (at least in analog design, but don't know about digital design) transistors are made with a longer gate than that for design requirements?
2)I am looking for a free software that would allow me to draw schematics, more specificly I would need fully differential opamp/OTA, some softwares I have found just do not have such elements (as https://www.schematics.com or https://www.circuit-diagram.org and are therefore useless for me).
Does anyone know such a software?
Thanks for helping
