Abstract

In this paper making use of the continuous behavior of the integrators of the continuous time delta sigma modulators (CT DSMs), a new circuit for the linearization of the multi-bit DAC of the modulator is proposed that compared to its traditional counterparts is much smaller. The required formulas for the linearization of the multi-bit DAC are derived and the validity of those is proven by MATLAB and HSPICE simulations
