A Fast Startup 38.4-MHz Crystal Oscillator Achieving 99-nJ Startup Energy With Adaptive Chirping

Shortening the startup time of a crystal oscillator is critical in improving the energy efficiency of the Internet of Things (IoT) sensor nodes. This article presents an investigative study on the application of adaptive chirping using zero-phase cross-detection to reduce the startup time of a cryst...
