Hi all,
What should be taken into account in designing a current mirror using subthreshold pmos, where Vds > 5*VT(26mv)?
Since the Vgs's control on Ids is much more stronger in subthreshold area than in saturate area, the current copy performance of current mirror using subthreshold pmos is better than using saturate pmos, is that correct?
Secondly, the gm reducing in subthreshold area does not matter in current mirror design.
What eles should be taken into account in this design?
