    Abstract: An AD converter includes a plurality of analog input terminals, a reference signal generation circuit that generates an analog reference signal, a sample-and-hold unit that includes a plurality of sample-and-hold circuits sampling the analog reference signal or one of analog input signals from the analog input terminals, a control unit that controls the sample-and-hold unit, and a conversion unit that converts an output signal from the sample-and-hold unit into a digital signal. The control unit controls the sample-and-hold unit to perform the output operation for analog input signal and the sampling operation for the analog reference signal.

    Abstract: A semiconductor device includes a semiconductor substrate, a first source region and a first drain region each formed from an upper surface of the semiconductor substrate, a first gate electrode formed on the semiconductor substrate between the first source region and the first drain region via a first gate dielectric film, a first trench formed in the upper surface of the semiconductor substrate between the first gate dielectric film and the first drain region in a gate length direction, a second trench formed in the upper surface of the semiconductor substrate between the gate dielectric film and the first drain region in the gate length direction, the second trench being shallower than the first trench, and a first dielectric film embedded in the first trench and the second trench. The first trench and the second trench are in contact with each other in a gate width direction.

    Abstract: The present document relates to a processing device and a method for performing time stamping of data at a high level of integrity such as ASIL (Automotive Safety Integrity Level) D. The processing device processes a data frame comprising data. Furthermore, upon reception of a trigger which is indicative of the processing of the data frame, the processing device captures a time stamp using a primary timer. Next, the processing device generates validation data based on the data frame and the time stamp. In addition, the processing device stores the validation data in conjunction with the data frame and the time stamp in a memory module.

    Abstract: A semiconductor device includes an analog-to-digital converter configured to perform a process of sampling an analog input signal and a successive-approximation process, execute an AD conversion process, and output a digital output signal. The AD converter includes an upper DAC, a redundant DAC, a lower DAC, a comparator configured to compare a comparative reference voltage and output voltages of the upper DAC, the redundant DAC and the lower DAC, a control circuit configured to control successive approximations by the upper DAC, the redundant DAC and the lower DAC based on the comparison result of the comparator, and generate a digital output signal, and a correction circuit. The correction circuit includes an error correction circuit configured to correct an error of the upper bit with the redundant bit, and an averaging circuit configured to calculate an average value of conversion values of a plurality of the lower bits supplied multiple times.

    Abstract: The semiconductor device includes a pair of gate-electrodes GE formed inside the pair of trenches TR via an gate insulating film (GI), respectively. The pair of column regions PC are spaced apart from each other in the Y-direction. The pair of trenches TR are provided apart from each other in the Y direction, are provided between the pair of column regions PC in the Y direction, and extend in the X direction. The ends of the pair of trenches TR in the X direction are connected to each other by a connecting portion TRa extending in the Y direction. The connection portion TRa is integrated with the pair of trenches TR. The pair of column regions PC extend in the X direction along the pair of trenches TR, and extend in the X direction toward the outer edge of the semiconductor substrate beyond the connection portion TRa.
