Resetting 2-Order Sigma -Delta Modulator in130 nm CMOS Technology

In current scenario, high-resolution ADC architecture based on a resetting modulator required high gain Operational Trans-conductance Amplifier (OTA) and quanitizer in low-voltage nanometer-scale CMOS processes because of good speed and calibration-free response are becoming more popular in communication system. Proposed paper achieves such high resolution, despite poor component matching using folded cascade OTA and two different 1-bit and 1.5-bit quantizer with switched capacitor Modulator design to reduced thermal noise and a possible optimization of power consumption.
