Fundamentals of Designing with Analog to Digital Converters
BACK BY POPULAR DEMAND: an update to The Fundamentals of the Analog to Digital Converter (ADC) webcast, including basic ADC architectures, understanding ADC errors, how to read an ADC data sheet, and how to choose the right ADC. Includes the latest on ADC products and technology.
Demystifying the JESD204B High-speed Data Converter-to-FPGA interface
This webcast will provide an overview of the JESD204 standard from its original version up to the current "B" revision. In addition, common "high-performance metrics" that are associated with high speed serial interfaces such as JESD204 will be described. Topics covered in this webcast will also be useful for applications that use similar high speed serial interfaces.
Webcast: The Latest on Driving ADCs Differentially: Part 2
This is the second of a two-part series addressing how to select the right differential ADC driver for your design. In part one we looked at the basics of driving ADCs, including errors in sampled data systems (such as distortion and noise) ENOB, differential signaling definitions, and advantages of ADC driver architectures. This month we will take these basic concepts and use them to make the driver selection and design driving circuits.
Webcast: Design Considerations for Multi-Channel ADCs
Our ADC expert will explore the important design considerations of multi-channel ADCs, both pro and con. Some tradeoffs of utilizing ADCs with additional on-chip functionality will also be discussed.
Designing Transformer Coupled Front-Ends for High Performance A/D Converters
This Webcast will provide a practical "formula" approach for designing transformer-coupled front-ends for high performance ADC in baseband and super-Nyquist applications.
Driving High Performance ADCs in Communication Applications
In this Webcast, our amplifier expert will review RF versus ADC terminology, provide a basic overview of system budgeting, contrast different ADC driver implementations, and touch on filter design techniques required to meet today's stringent system requirements.
