How Quantization and Thermal Noise Determine an ADC's Effective Noise Figure

资料介绍
Abstract: The following application note provides an insight into the mathematical definitions of quantization and thermal noise, parameters which can significantly affect the signal-to-noise ratio (SNR) and signal-to-noise plus distortion (SINAD) specifications of analog-to-digital converters (ADCs) in RF receiver applications. It concludes by comparing their impact on the effective noise figure for a Nyquist and oversampling ADC.
