High-resolution Time-interleaved Delta-Sigma Modulator using Inverter-based Integrator

Abstract

This paper proposes High-resolution Time-interleaved Delta-Sigma modulator using inverter-based integrator. These days, Analogue and digital converters (ADC) commonly used in many electronic device essential parts. Research has been carried out on high performance ADCs in accordance with the intensive development of technology. However, as the limitation of the fabrication technology, the design of high gain and low power Op-amps becomes very difficult. For that reason, suggesting Time-interleaved Delta-sigma modulators (DSM) composed inverter-based integrators. Those are makes it possible to reduce the power consumption and enhance the operating speed through the parallel architecture. This ADC has been designed with 0.18 um CMOS process by magna, and simulation performed by Cadence Virtuoso Spectre circuit simulation and MATLAB.
