A phase-locked loop (PLL) is a feedback system that combines a voltage-controlled oscillator (VCO) and a phase detector in such a way that the oscillator signal tracks an applied frequency or ...

Today, a growing number of micro-manufactured actuators, sensors, and components vibrate at frequencies in the high MHz range. Some examples of such high-frequency vibrating systems are ...

This is Part 2 of a three-part series. As discussed in Part 1 and recapped here, modern wireless communications systems (mainly superheterodyne radio transceivers) are now required to deliver higher ...
