Energy Efficient Startup of Crystal Oscillators Using Stepwise Charging

Crystal oscillators can be started up quickly by using energy injection techniques. However, the generation of the injection waveform, as well as driving the large capacitive load formed by the crystal, costs a large amount of energy. This article applies the concept of stepwise charging to reduce t...
