With the rapid development of Internet of Things (IoT) technology, low-power, fast start Crystal Oscillators (CO) play a crucial role in various electronic devices. However, traditional crystal oscillators suffer from long start-up time and high energy consumption during the start-up process, which limits their application in low-power devices. To address this issue, this paper proposes a fast start crystal oscillator design based on dual-mode adaptive switching. This design significantly reduces startup time and energy consumption by optimizing the startup process, and improves overall system performance. This article provides a detailed analysis of the working principle of the dual-mode switching mechanism, including the design of coarse adjustment mode and fine adjustment mode. Through theoretical derivation and simulation verification, it demonstrates the significant advantages of this design in improving startup speed.
