Touchscreen technology plays an important role in the booming mobile devices market. Traditional touchscreen only provides 2D interactions with limited user experience. To overcome these limitations, we propose a novel 3D touch sensing system called the Airtouch system, which can recognize the movement of the finger in a 3-dimensional space. Half of the(More)
This paper presents a novel self-equalized and skewless frequency-division multiplexing memory interface. To prove its feasibility, we have realized a 5-band QPSK transceiver in 40 nm CMOS to transmit up to 4 Gb/s through 10 orthogonal communication channels (each with 400 Mb/s) via on-chip TSV emulator with effective loading of 1 pF or 5-cm FR-4 PCB trace.(More)
