Fast Switching Speed

We investigate a cascode configuration of a normally-on SiC-Buried Gate Static Induction Transistor (SiC-BGSIT) and Si-MOSFET as an alternative switching device of the SiC-MOSFET. It is shown that the transconductance of our cascode device is much higher than that of commercial SiC-MOSFETs while the switching speed is much faster than that of normally-off SiC-BGSITs. The origin of the fast switching speed in this cascode configuration is discussed in terms of a simulated reverse transfer capacitance.

Frequency synthesizer – as a main module for modern communication systems, test-and-measurement equipment and other electronic devices – should meet certain requirements. The most important requirements include spectral purity of generated signal (low phase noise and spurs), fast switching speed and high frequency resolution (low step size). Other important characteristics include low power consumption, small size and low cost. Thus, the main design goal is selecting proper solutions to support these requirements. This article describes various architectures used to design frequency synthesizers based on phase locked loop.
