hi kidman, Based on the application type mirror being used is decided,for example in differential amplifiers if the i/p variations are not much then simple mirror is the first choise,but if u want really high CMRR then u have to go for cascode.again cascode consume a lot of headroom for voltege,in that case high swing mirror is the best choice.This information u can get from razaavi.
Thank you.
