DOI: 10.1007/s00034-018-0887-4
Abstract: This paper describes a symmetric phase frequency detector (PFD). The symmetric structure of PFD provides phase-locked loop (PLL) functions with a low jitter. The most important point in designing PFDs is attention to their dead… read more here.

DOI: 10.1134/s1064226919020050
Abstract: It is shown that the phase–frequency characteristic (PFC) of an analog filter connected to an ADC can be linearized with the aid of a digital filter with a finite impulse response (FIR). Circuit simulation is… read more here.
