Quartz crystals have dominated the timing market for the last 70 years. FBAR technology is poised to replace quartz for many high frequency applications. Integration of the ultra-small form factor of the microcap’d FBAR into the SoC BGA packages cu

Highly miniaturized wireless sensors will enable new healthcare sensing modalities such as ultra-small wearables, implantables, smart pills, etc. Bluetooth Low Energy (BLE) links to sensors improves user experience but necessitate a highly integrated

We present an oven-controlled FBAR oscillator that achieves a frequency stability of +/-1.55ppm from -5°C to 85°C. The highly integrated system includes a 0.64mm2 FBAR chip with integrated heater and sensor resistors and a 3 mm2 CMOS chip with the

The first fully integrated oven-controlled temperature compensation system with the transformer coupled Colpitts oscillator is developed by 65nm CMOS tech. This work achieves ±1.55ppm frequency stability over the 85°C temperature range which can be

Recent work with chip scale integrated FBAR oscillators has highlighted the fact that the temperature sensitivity is similar to SAW resonators. This sensitivity is significantly higher than quartz crystal oscillators, and limits the application of th

Multiple emerging wireless applications (body-worn devices and IoT, for example) will demand previously impossible thin-film form factors and low system cost. One key enabling technology for this paradigm is a new class of radios that offer cost/size

Supply-noise measurement techniques are becoming increasingly critical in modern digital design, driven by the trend toward smaller, lower-voltage domains. All-digital measurement modules capable of meeting bandwidth and resolution requirements would

We present a technique to reduce the close-in phase noise of high-Q (FBAR/MEMS/crystal) oscillators. The proposed technique suppresses the up-conversion of 1/f noise via AM-PM conversion by the addition of a non-linear capacitor to the tank. The prop
