Primary design considerations for fundamental-mode oscillators using AT-cut crystals include load capacitance, negative resistance, startup time, frequency stability versus temperature, drive-level ...

Starting a crystal oscillator fast in an IoT node is an art: the high Q needed for stability means they take milliseconds to get going, just to transmit a 128μs Bluetooth LE packet, and power is at a ...

This tutorial explains the primary design considerations to be addressed in a design of a simple crystal oscillator using AT-cut crystals. The basic qualities of a crystal oscillator and factors that ...
