Abstract

In this paper, a high-resolution multibit sigma-delta modulator implemented in a.0.35-um CMOS technology is introduced. This modulator consists of two switched capacitor integrators, 3-bits A/D converter, and 3-bits D/A converter For the verification of the internal function blocks, HSPICE simulator is used. This circuit is normally operated at 130 MHz clock and the total power dissapation is 70 mW.
