hi,
I'm currently building a two stage opamp and I'm using the basic NMOS current mirror topology(current sinking) as it was the most used topology. However, I'm not sure why I should use NMOS current mirror topology over PMOS current mirror topology(current sourcing) and it would be grateful If some can provide me some reasoning and any advantages of using the NMOS current mirror topology for a two stage opamp.
