Abstract :
This work presents the rigorous formulation of input referred offset voltage for differential amplifier, having the input pair devices in subthreshold region of operation. The formulation has been verified in 0.35 μm and 0.18 μm CMOS technologies by using Monte Carlo Simulation. Minimization of 1/f noise is the additional advantage of this method.
