This paper presents an integrated crystal oscillator to provide a 55 MHz reference frequency for applications such as phase-locked loops. The crystal oscillator uses a Pierce oscillator architecture and achieves a phase noise of -152 dBc/Hz at 1 kHz offset. A chirp frequency injection technique is also applied, achieving a start-up time of 300 us with 335 nJ energy consumption. The circuit is
