  • Abstract
    A high-resolution second-order integrating sigma-delta analog-to-digital converter (ADC) using double-sampled integrators is presented whitch performs two times faster sampling than conventional modulator. The modulator has been designed in a 0.18-um CMOS technology. It acheives a signal-to-noise and distortion ratio (SNDR) of 93.03 dB at a conversion rate of 64 sample/s. Power dissipation is 36μW for a single supply voltage of 2.0V. Active area of prototype ADC is 0.396μm2.
