In particular, the disclosed systems can dynamically evolve metadata for data files of various machine learning datasets and independently manage storage locations across digital repository platforms by maintaining and utilizing a centralized cross-platform metadata database and corresponding cross-platform file location database.

Abstract: The present disclosure relates to systems, non-transitory computer-readable media, and methods for generating and displaying compatibility metrics between experiment designs and data analysis models. For example, the disclosed systems can display an experiment design user interface that enables user selections of a modular experiment design and data analysis models for the experiment design.

Abstract: A power amplifier apparatus is provided. The power amplifier apparatus includes a number of multi-stage power amplifiers and a bias circuit configured to generate a number of bias signals (e.g., bias current or bias voltage) to control (e.g., activate or deactivate) the multi-stage power amplifiers. In examples disclosed herein, only one of the multi-stage power amplifiers is activated at a given time. In this regard, the bias circuit can generate the bias signals to collectively activate one of the multi-stage power amplifiers, while deactivating the rest of the multi-stage power amplifiers. As such, it may be possible to control a larger number of power amplifier stages based on a smaller number of bias signals. As a result, it may be possible to eliminate a biasing bump pad(s) from the power amplifier apparatus, thus helping to reduce the footprint and cost of the power amplifier apparatus.

Abstract: Bias circuitry is disclosed with a bias drive device having a first current terminal coupled to a voltage supply node, a bias control terminal coupled to a control node, and a second current terminal coupled to a bias output node. An impedance control device has a third current terminal and an impedance control terminal that are coupled together and a fourth current terminal coupled to ground. An output impedance resistor is coupled between the third current terminal and the bias output node. A pull-down device is coupled between the bias output node and the fixed voltage node, wherein a higher voltage applied to the control node sets an output impedance at the bias output node to approximately a lower impedance of the pull-down device and a lower voltage applied to the control node sets the output impedance to approximately the resistance of the output impedance resistor.
