All-Digital RF Phase-Locked Loops Exploiting Phase Prediction
This paper presents an all-digital phase-locked loop (ADPLL) architecture in a new light that allows it to significantly save power through complexity reduction of its phase locking and detection mechanisms. The predictive nature of the ADPLL to estimate next edge occurrence of the reference clock is exploited here to reduce the timing range and thus complexity of the fractional part of the pha...
متن کاملLow Jitter Low Power Phase Locked Loops Using Sub - Sampling Phase Detection
A periodic clock signal is required in many ICs. These clocks are for instance used to define the sampling moments in data converters; to up-convert and down-convert the wanted signals in wireless transceivers and to synchronize the data flow in wireline and optical serial data communication links. The clock timing/phase accuracy affects the overall system performance and therefore a clock gene...
متن کاملPhase - Locked Loops Demystified
Over the past decade, Phase-Locked Loops (PLLs) have become an integral part of the modern ASIC design. PLLs provide the clocks that sequence the operation of the various blocks on an ASIC chip as well as synthesize their communications. There are various types of PLLs targeting specific applications. Clock generator PLLs are capable of large frequency multiplication. They are primarily used to...
متن کاملBalanced optical-microwave phase detectors for optoelectronic phase-locked loops.
A balanced optical-microwave phase detector for the extraction of low-jitter, high-power, and drift-free microwave signals from optical pulse trains is presented. The phase detection is based on electro-optic sampling with a differentially biased Sagnac loop. Because the timing information is transferred in the optical domain, the regenerated microwave signal is robust against drifts and photod...
متن کاملPhase-Locked Loops: A Control Centric Tutorial
This paper will present a tutorial on phase-locked loops from a control systems perspective. It will start with an introduction of the loop as a feedback control problem, with both the similarities and differences to traditional control problems. Chief among the differences is the necessary inclusion of two nonlinearities in the loop that are not parasitic, but essential to the loop’s operation...
