Simulation of High Performance Pipelined ADC Based on Optical Component Using VHDL

— This thesis explores the high performance ADC based on optical component. This research work presents a two stage pipelined ADC that is basically a broadband high sampling rate ,high resolution and high speed application. which incorporates a Flash ADC using optical components like optical source and optical detector. The application of this methodology not only enhanced sampling rate but also minimizes the power consumption and hardware of the structure. Traditionally, electronic component based flash ADC were used, but the drawback with such ADC was the increased propagation delay and low resolution. To get rid of this drawback, in this research work the electronic component are replaced by optical source and array of optical detectors. In this thesis the comparison of electronic component based pipelined ADC with optical component based pipelined ADC is shown. For evaluation of the parameter VHDL code is implemented the analysis results are shown that our analog to digital converter scheme is promising to achieve high resolution of up to 12 bit at the sampling rate of approximate 8 GSPS .
