Voltage controlled oscillators (VCOs) are one of the most sensitive circuit block to electromagnetic noise. The phase noise of VCOs depends on the time when the noise is injected, so it has time-variant nature to electromagnetic interference (EMI). In this paper, we apply the phase noise theory in analyzing the electromagnetic susceptibility (EMS) of phase noise in VCOs in presence of noise in power...
This paper presents a wide frequency range CDR circuit for second generation AiPi+ intra-panel interface. The speed of the proposed clock and data recovery is increased to 1.25 Gbps compared with conventional AiPi+. The DLL-based CDR architecture is adopted to generate multi-phase clocks. We propose a simple scheme for a frequency detector (FD) to overcome the limited frequency range and false lock...
