Phase noise and the noise floor of signals are fundamental properties and constant challenges in radio and radio network design. Phase noise affects not only the received signal's jitter, signal...
In ADC applications, increased phase noise can limit the signal-to-noise ratio (SNR) and equivalent number of bits (ENOB) of the data converter. Phase noise is the frequency domain representation of clock noise. Phase jitter, on the other hand, is the time domain instability of the clock ...

noise figure is the SNR (signal-to-noise ratio) at the output of a component or block compared to the SNR at the input of the component or block.
Phase noise causes significant degradation in the performance of orthogonal frequency division multiplexing (OFDM)-based wireless communication systems. The presence of phase noise can reduce the effective signal-to-noise ratio (SNR) at the receiver, and consequently, limit the bit error rate (BER) ...
of electrical performance or functionality. In order to meet these requirements, including an improved signal-to-noise ratio (SNR), bit error rate (BER), and the high quality of service (QoS) that users are accustomed to, the phase noise of the local oscillator (LO) must improve as well....
MT-008 TUTORIAL Converting Oscillator Phase Noise to Time Jitter by Walt Kester INTRODUCTION A low aperture jitter specification of an ADC is critical to achieving high levels of signal-to- noise ratios (SNR). (See References 1, 2, and 3). ADCs are available with aperture jitter ...
If the noise terms are uncorrelated (c = 0), the noise will increase 10logN. With the signal level increasing at a 20logN rate (10logN greater rate than the noise), the resulting SNR improvement is 10logN. If the noise terms are correlated (c = 1), the noise will also increase...
