Why Voltage-Reference Noise Matters

The voltage reference sets the limit to the input analog signal that the ADC can resolve. Equation 1 is the ideal transfer function of an ADC where the output code—in decimal form—is computed by the ...

ADC programmable digital gain allows tradeoffs in SNR and distortion performance

The achievable signal-to-noise ratio (SNR) and distortion performance of high-speed analog-to-digital converters (ADCs) is directly related to the full scale voltage swing of the analog input. A ...

Fully Digital Implemented Delta-Sigma Analog to Digital Converter

One of the most challenging tasks in Analog to Digital Converter (ADC) design is to adapt the cicuitry to ever new CMOS process technology. For digital circuits the number of gates per square mm app.

Using input-referred noise to improve analog-to-digital converter resolution

All analog-to-digital converters (ADCs) have a certain amount ofinput-referred noise. In most cases,less input noise is better. There are some cases, however, where inputnoise can actually be helpful ...

Leveraging FPGA and CPLD digital logic to implement analog to digital converters

Designers of digital systems are familiar with implementing the 'leftovers' of their digital design by using FPGAs and CPLDs to glue together various processors, memories, and standard function ...
