The Y-factor method simplifies noise figure measurements by allowing the use of variable attenuators in place of a calibrated power meter. In addition to defining the Y factor, we will discuss noise source uncertainty and fixturing losses that can introduce errors in your noise figure measurements.

Fari Assaderaghi and SiTime are aiming to disrupt the 70-year-old quartz timing industry by replacing crystals with silicon MEMS. After nearly two decades of following “Moore’s Law for timing improvements,” their time may have finally arrived.

This project demonstrates the design and operation of a root-mean-squared (RMS) detector for inclusion in a wideband voltmeter. The RMS detector is useful for measuring certain signal types, including noise, since it provides an indication of the energy in a signal.
