Abstract

In this paper, a new structure of delta sigma modulator has been proposed in which a second order filter in one stage technique has been taken into the account and a second order noise shaping method and a third order one have been designed by the proposed idea. In the proposed structure an OPAMP has been saved and since in a conventional delta sigma modulator OPAMPs consumes most of the power and takes very large area, the proposed idea causes less power consumption and also the chip area is minimized.
