Designing an Integrated All-Optical Analog to Digital Converter
We present the procedure for designing a high speed and low power all-optical analog to digital converter (AO-ADC), by integrating InGaAsP semiconductor optical amplifier (SOA) with InP based photonic crystal (PhC) drop filters. The self-phase modulation in the SOA can shift the frequency of the Gaussian input pulse. The two output PhC based drop filters are designed to appropriately code the f...
متن کاملsignal specific successive approximation analog to digital converter
چکیده: در میان انواع متفاوتی از مبدل های آنالوگ به دیجیتال که تا کنون معرفی شده اند، مبدل های آنالوگ به دیجیتال تقاریب متوالی(sar ) به علت سادگی ساختار و همچنین توان مصرفی کم، همواره یکی از پرکاربرد ترین مبدل های آنالوگ به دیحیتال در کاربرد های بایومدیکال بوده اند. به همین دلیل تاکنون روش های متعددی برای کاهش هرچه بیشتر توان مصرفی در این مبدل ها ارائه شده است که در اکثر آنها توجهی به مشخصات سی...

Analog-to-digital converters are essential building blocks in modern electronic systems. They form the critical link between front-end analog transducers and back-end digital computers that can efficiently implement a wide variety of signal-processing functions. The wide variety of digitalsignal-processing applications leads to the availability of a wide variety of analog-to-digital (A/D) conve...
متن کاملOptimal fast digital error correction method of pipelined analog to digital converter with DLMS algorithm
In this paper, convergence rate of digital error correction algorithm in correction of capacitor mismatch error and finite and nonlinear gain of Op-Amp has increased significantly by the use of DLMS, an evolutionary search algorithm. To this end, a 16-bit pipelined analog to digital converter was modeled. The obtained digital model is a FIR filter with 16 adjustable weights. To adjust weights o...
متن کاملAnalog-to-digital converter testing - new proposals
New static and dynamic analog-to-digital converter (ADC) testing techniques are revised and discussed. A new test method based on the Histogram Method but using small-amplitude triangular waves with a variable offset is shown to have several advantages over the traditional static test, namely a dramatic reduction in test duration even for highresolution ADCs. The use of Gaussian noise to stimul...
