- Abstract
- Based on mismatch measurements performed on very different CMOS technologies and large operating temperature range, we propose to model more adequately the mismatch in weak and moderate inversion by adding a new term related to the mismatch of the body effect factor dependence on the gate voltage. The model is introduced in a top-down analog design methodology, applied to the current mirror case, revealing some nonobvious design rules as well as typical misconceptions.
