متن کاملUltra-high Speed A/D Converters Using Zero-crossing-based Circuits
With an increasing need for higher data rates, both wireless applications and data links are demanding higher speed analog-todigital converters (ADC) with medium resolution. In particular, this work will investigate ADC’s with sampling rate up to 10 Gs/s with 6-8 bits of resolution. Time-interleaved converters achieve their high sampling rate by placing several converters in parallel. Each indi...
متن کاملAn Interleaved Configuration of Modified KY Converter with High Conversion Ratio for Renewable Energy Applications; Design, Analysis and Implementation
In this paper, a new high efficiency, high step-up, non-isolated, interleaved DC-DC converter for renewable energy applications is presented. In the suggested topology, two modified step-up KY converters are interleaved to obtain a high conversion ratio without the use of coupled inductors. In comparison with the conventional interleaved DC-DC converters such as boost, buck-boost, SEPIC, ZETA a...
متن کاملA Survey of Filter Bank A/d Converters
Hybrid filter bank analog-to-digital converters (ADCs) have been proposed as a candidate for high-speed, high-resolution analog-to-digital conversion. It is a generalization from time-interleaved ADCs, but it has the advantage that the mismatch errors inherent in parallel converters are attenuated by the filters. This paper gives an overview of hybrid filter bank ADC analysis and design. Furthe...
