A low-energy self-synchronous serial link receiver for inductive coupling communication is implemented in 130nm CMOS process. The gated-ring oscillator (GRO) is proposed to combine three key building blocks (CDR, phase interpolator and PLL) used in conventional receiver resulting in energy consumption reduction. In addition, the start-up time and settling time for clock recovery can be significantly...
Recently, short distance board-to-board interconnections are widely employed in portable systems and wearable devices to accommodate many components into an extremely tight footprint. In particular, portable devices such as smart phone and tablet require over 1Gb/s data transfer through ∼1mm distance between AP board and a high resolution wide screen display board. Most of display interfaces are implemented...
Iontophoresis enhances drug penetration non-invasively into body tissue by electrical stimulation [1]. Compared with injection and oral dosage, it has advantages in the ease of use, the minimization of side effects, such as pain, infection and hepatic first-pass effect, and the targeted drug delivery with precise dosage. Especially, the drug dosage can be easily controlled by changing the stimulation...
A compact electro-acupuncture (EA) system is proposed for a multi-modal feedback EA treatment. It is composed of a needle, a compact EA patch, and an interconnecting conductive thread. The 3 cm diameter compact EA patch is implemented with an adaptive stimulator IC and a small coin battery on the planar-fashionable circuit board (P-FCB) technology. The adaptive stimulator IC can form a closed current...
