Variability-aware design method for a constant inversion level bias current generator
Resumen:
A model for estimating the dispersion in the output of a MOS-only, constant inversion level, current reference is presented. Based on such model, a design method is introduced that allows to minimize dispersion for a given layout complexity. The method was applied to five different designs producing currents from 2.4 nA to 4.2 nA (@ 300 K) and simulated dispersions with Cadence Spectre ranging from 1.3% to 1.5% (1 σ) while the model predicted dispersions from 1.2% to 1.4%.
