A device may generate, using a random telegraph signal (RTS) noise generator, a simulated RTS noise as input to a transistor included in an electronic circuit. The device may determine, based on the simulated RTS noise input to the transistor, a simulated output signal from the transistor.

A method to determine noise parameters of a scalable device, is presented in which the determination of the noise parameters of the scalable device is independent of the model adopted for the device. The scalable device is connected as part of a test circuit including a noise source, a recirculator, a first power detector and a second power detector. The first power detector is connected to the recirculator and between the noise source and the scalable device and the second detector is connected to the device under test.

Apparatuses of a noise measurement system and methods for using the same are disclosed. In one embodiment, a noise measurement system may include a plurality of probe groups electrically coupled to a plurality of DUTs, where a probe group in the plurality of probe groups includes multiple channels, and where the multiple channels of each probe group are bundled as a group for reducing electromagnetic interference among the plurality of probe groups, and wherein the group is shielded from corresponding signal groups of other DUTs with a connection to a circuit ground of the noise measurement system for reducing ground loop generated signal interference. The noise measurement system may further include a controller configured to perform noise measurement.

A noise parameter test setup allows accurately measuring the four noise parameters (Fmin, Rn, opt) of microwave transistors over a wide frequency range using two wideband directional couplers, instead of SPDT switches, to merge the s-parameter (signal) measurement path and the noise measurement path, avoiding thus the uncertainty of the switching repeatability of the SPDT switches and improving the measurement accuracy. Calibration of the system is the same as when using switches. Additional power control precautions of the VNA sources are necessary to avoid injecting large signal power into the sensitive noise receiver during s-parameter measurements and jamming the weak noise power during noise measurement.
