Abstract :
This paper describes two novel phase-frequency detectors. The first one overcomes the non-linear transfer characteristic found in many conventional phase-frequency detectors and thus results in a PLL-VCO with low phase noise. The second phase-frequency detector can be used in a phase locked loop (PLL) to recover the carrier of a binary phase shift keyed (BPSK) signal, thus permitting the BPSK data to be demodulated with hardware that is significantly simpler and performs better than the Costas loop (Costas, 1956)
