Oscillator Phase Noise: A Tutorial
Oscillator Phase Noise: A Tutorial

... Such a floor may be due to the noise associated with any active elements (such as buffers) placed between the tank and the outside world, or it can even reflect limitations in the measurement instrumentation itself. Even if the output were taken directly from the tank, any resistance in series with ...

... The LNA has a single-ended-to-differential gain that is selectable through the SPI. The LNA input noise is typically 0.75 nV/√Hz at a gain of 21.3 dB, and the combined input-referred noise of the entire channel is 0.85 nV/√Hz at maximum gain. Assuming a 15 MHz noise bandwidth (NBW) and a 21.3 dB LNA ...

Tutorial on Single-Pole Tripping and Reclosing

... Abstract—Power systems are being operated closer to their stability limits, and fewer transmission lines are being built to accommodate the growing demand for power. A fault on a transmission system significantly impacts the power transfer capability of the power system. Taking a line out of service ...

Bode plot



In electrical engineering and control theory, a Bode plot /ˈboʊdi/ is a graph of the frequency response of a system. It is usually a combination of a Bode magnitude plot, expressing the magnitude of the frequency response, and a Bode phase plot, expressing the phase shift. Both quantities are plotted against a horizontal axis proportional to the logarithm of frequency.
