ISDL has studied on various VLSI designs, especially, focusing on high-speed communication system. First, we are mainly working on high-speed I/O interfaces such as an optical link and a graphic interface. Next, we are also interested in capacitive sensing circuits such as a digital microphone and a touch screen controller. Recently, power ICs, which convert supply voltage level according to applications, are also studied. These power circuits mainly target LED driver unit. Finally, we have a research on transceiver for RF module and All-digital PLL replacing analog blocks with digital blocks to overcome difficulty of analog circuit design in DSM technologies.
