Although a simple crystal oscillator may be built from one comparator of an LT1720/LT1721, this will suffer from a number of inherent shortcomings and design problems. Although the LT1720/LT1721 will ...

Fast comparators find their niche in linear applicationsComparators don’t “just compare” in the same way that op amps don’t “just amplify.” A collection of application circuits demonstrates just how ...

In this paper an All Digital phase locked loop is proposed. This PLL can accomplish faster phase lock. Additionally, the functions of frequency comparator and phase detector have been improved and are ...

Voltage comparators began appearing in single-chip microcontrollers (MCUs) in the late 1990s. At the time, the change was viewed as a simple cost reduction. Comparators required less silicon, while ...

If you want a stable oscillator, you usually think of using a crystal. The piezoelectric qualities of quartz means that it can be cut in a particular way that it will oscillate at a very precise ...
