Abstract:

Ast start-up crystal oscillators (XOs) based on energy injection with an auxiliary oscillator (AO) are efficacious in improving the energy consumption of duty-cycled the Internet of Things (IoT) devices. Nonetheless, the frequency mismatch ( $Delta$ F) between the injection frequency and the crystal’s resonance frequency restrains the injection efficiency and …
