Analog/Mixed Signal Design Services
Having inherited analog circuit technology from the bipolar IC generation, we have been expanding our technological fields to include BiCMOS and CMOS analog LSI. We respond flexibly to customer requests through a development system that covers specification determination, circuit design, layouts, design verification and initial evaluation according to the characteristics of the product in question. We contribute to the development of LSI for the IoT, which is expected to be widely used in the future, through mixed-signal designs that mix logic design with analog peripheral circuits for sensors—an area where we have a great deal of expertise—and AD/DA conversion circuits.
