Kanemoto D., Ido T., Taniguchi K.. A novel third order Delta Sigma Modulator with one opamp shared among three integrator stages. IEICE Electronics Express 5, 1088 (2008); https://doi.org/10.1587/elex.5.1088.
Abstract
A novel third order delta sigma modulator (DSM) is presented. The third order loop filter in the proposed DSM shares one opamp among three integrator stages through an optimal operation timing, which makes use of load capacitance differences between integrator stages. The power dissipation of the proposed DSM is much lower than conventional third order DSM because power consuming blocks in the DSM are only one opamp and a comparator. The proposed DSM, designed on 0.35 μm CMOS process under 3.3 V supply achieves 1 mW power dissipation with 100-11 kHz band width and 96 dB SQNR.
