Latest Patents
Shimazu's latest patents include a semiconductor integrated circuit device for television and an output processing circuit for radio frequency receivers. The semiconductor integrated circuit device is designed to generate various signals for television. It features a switch circuit that allows for the selection of a monitored signal from multiple options, outputting the selected signal through an external terminal. A microcomputer supplies a selection signal to the IC, which compares the selected signal data with pre-prepared data. Based on this comparison, the IC renews the adjustment data used for generating the corresponding signal.
The output processing circuit for radio frequency receivers comprises a level detector that detects the signal level corresponding to the intensity of the reception electric field. It includes a gradient controller that adjusts the signal level detected by the level detector to match the electric field intensity. Additionally, a potential slider with a variable level shifter is incorporated to shift the detected signal level by a predetermined amount. The output control circuit processes the reception signal according to the output level from the potential slider, ensuring optimal performance.
