But if u want your current mirrors can get better performance in practice, I think BJTs is indispensable.aryajur said:Is it better to implement Current Mirrors using MOS or BJTs in a BiCMOS process? One reason I can think in favor for MOS is that there is no gate current so the mirroring will be more accurate compared to the Base current error of BJTs. Are there any other important reasons?

They are used to get a low temperature coefficient.aryajur said:qiushidaren said:But if u want your current mirrors can get better performance in practice, I think BJTs is indispensable.
Sorry, I didn't understand the reason, why are BJTs (used as mirrors) better in 1st circuit below?
