    Abstract: A parameter candidate for a semiconductor element is provided. A data set of measurement data is provided to a parameter extraction portion, and a model parameter is extracted. A first netlist is provided to a circuit simulator, simulation is performed using the first netlist and the model parameter, and a first output result is output. A classification model learns the model parameter and the first output result and classifies the model parameter. A second netlist and a model parameter are provided to the circuit simulator. A variable to be adjusted is supplied to a neural network, an action value function is output, and the variable is updated. The circuit simulator performs simulation using the second netlist and the model parameter. When a second output result to be output does not satisfy conditions, a weight coefficient of the neural network is updated. When the second output result satisfies the conditions, the variable is judged to be the best candidate.

    Abstract: To provide a highly secure electronic device. The electronic device includes a control portion, a detection portion, and a memory portion. The detection portion has a function of detecting touch operation and a function of obtaining first finger data on a touching finger. The memory portion has a function of retaining second finger data registered in advance. The control portion has functions of comparing the first finger data with the second finger data and executing predetermined processing when these data match. The first finger data includes first fingerprint data and first positional data, and the second finger data includes second fingerprint data and second positional data.

    Abstract: Common noise is reduced from light-receiving data. A display module includes a display apparatus and a reading circuit. Each of a first pixel and a second pixel adjacent to each other in the display apparatus includes a light-receiving element and a light-emitting element. The reading circuit includes a differential input circuit. Common noise generated when display data is supplied to a light-emitting element, for example, may affect a first light-receiving signal output by the first pixel and a second light-receiving signal output by the second pixel. A first current is generated using the first light-receiving signal and a ramp signal, and a second current is generated using the second light-receiving signal and a first potential. The differential input circuit is controlled so that the first current and the second current have the same current value, whereby common noise can be removed from the first light-receiving signal.
