Abstract—An intuitive high-level argument is presented suggesting that direct-sampling radio frequency (RF) receivers using Nyquist analog–digital converters can be as power-efficient as analog heterodyne receivers for equal dynamic range specificat
JESD204B (Subclass 1) coded serial digital outputs 2.0 W total power at 1 GSPS (default settings) 1.5 W total power at 500 MSPS (default settings) SFDR = 85 dBFS at 340 MHz, 80 dBFS at 985 MHz SNR = 65.3 dBFS at 340 MHz (AIN = −1.0 dBFS), 60.5 dBFS
简单地说,分贝就是放大器增益的单位。放大器输出与输入的比值为放大倍数,单位是“倍”,如10倍放大器,100倍放大器。当改用“分贝”做单位时,放大倍数就称之为增益,这是一个概念的两种称呼。
电学中分贝与放大倍数的转换关系为:
AV (dB) = 20 lg ( Vo / Vi )
AI (dB) = 20 lg ( Io / Ii )
Ap (dB) = 10 lg ( Po / Pi )
分贝定义时电压(电流)增益和功率增益的公式不同,但我们都知
