The purpose of a phase locked loop (PLL) is to generate a frequency and phase-locked output oscillation signal. To achieve this goal, prior art essentially functioned ...

One of the most challenging tasks in analog circuit design is to adapt a functional block to ever new CMOS process technology. For digital circuits the number of gates per square mm approx. doubles ...

The performance of analogue phase-locked loops (PLLs) has steadily improved with operating frequencies extending to 8GHz and beyond. Recently, digital PLLs based on direct digital synthesis (DDS) have ...

Scientists have developed an advanced phase-locked loop (PLL) frequency synthesizer that can drastically cut power consumption. This digital PLL could be an attractive building block for Bluetooth Low ...

In sensitive optical applications, obtaining the most precise measurements often involves stabilizing the laser with an external reference. One way to synchronize the phase of a signal is by using a ...
