Radar Waveform Generator with Fuzzy Frequency Regulation [PDF]
International Journal of Telecommunications: The Phase-Locked Loop (PLL) is a common functional component in many electrical systems. Phase-locked loops (PLLs) are closed-loop feedback-driven devices producing a signal depending on the frequency and phase of reference sig-nal that comes in.

Interface electronics for a CMOS electrothermal frequency-locked-loop
ESSCIRC 2007 - 33rd European Solid-State Circuits Conference, 2007 This paper describes a new implementation of a CMOS electrothermal frequency-locked-loop (FLL), whose output frequency is determined by the temperature-dependent phase shift of an electrothermal filter (ETF). The FLL maintains a constant phase shift in the ETF, and as a result drives it with a signal whose frequency is a well-defined function of ...

Design and verification of data acquisition clock circuit based on dual-loop phase-locked loop
He jishu, 2022 Background Digital measurement system based on ADCs (analog-to-digital converter) has higher requirement on the signal to noise ratio (SNR) of sampled data. Among all the factors, the jitter of sampling clock has the most prominent effect on SNR.
