Testing High Frequency ADCs and DACs with a Low Frequency Analog Bus

High Performance Digital Signal Processing

Recent improvements in the speed and complexity of commercially available digital signal processing (DSP) devices have allowed digital techniques to be extended to a number of new areas. Now many applications in RF and communications are within the bandwidth capability of current generation DSP systems. This paper demonstrates a system developed recently for such applications. It uses standard ...

Wideband Modem Design Using FPGAs

1. ABSTRACT New waveform requirements are pushing the limits of traditional modem design techniques. Fortunately, modern Digital-to-Analog Converter (DAC) and Analog-to-Digital Converter (ADC) can achieve sampling rates in the GHz range. These new DACs and ADCs allow designers to directly synthesize channels that have bandwidths of more than 500 MHz+; allowing either wideband or multi-channel m...

Nyquist-rate digital-to-analog converter architectures - IEEE Potentials

he ever-dropping cost of Very Large Scale Integrated (VLSI) circuits allows many analog functions to be done digitally. However, the real world still is, and will always continue to be, a fundamentally analog place. Thus, the analog signal of interest is translated into a format that a digital computer can utilize. This translation is the function of an Analog to Digital Converter (ADC). After ...

A Deterministic Dynamic Element Matching Approach for Testing High Resolution ADCs Using Low Accuracy DACs (Design Number: 68091)

SPI MASTER CORE VARIFICATION USING SYSTEM VERILOG VARIFICATIONx

SPI (Serial Peripheral Interface) Master Core is used for connection between different devices. Synchronous serial interface are widely used to provide economical board-level interface between different devices such as microcontrollers, DACs, ADCs and other, although there is no signal standard for a synchronous serial bus. Many IC manufacturers produce components that are compatible with SPI. ...
