These nodes usually consist of a processor, memory, radio, sensors, battery, and two quartz crystals: one at 32kHz to synchronize data transmission and the other in the MHz range to synthesize RF signals. SoC integration of the memory, processor, and radio is common; however the MHz crystal remains external, which makes up a significant portion of the entire wireless node size. MEMS resonators are logical alternatives to replace external crystals due to their miniaturization and potential to be co-packaged with the SoC. One promising technology is the bulk acoustic wave (BAW) oscillator [1]. Despite multiple
