چکیده
This paper presents a system for simultaneous wireless power and data transfer (SWPDT) over single inductive link. We design the frequency-splitting link to address trade-off between high efficiency (PTE) rate (DR). An active rectifier is designed conversion efficiency. Forward communication based on frequency-shift keying (FSK) modulation support DR transmission while delivering uninterrupted power. Moreover, we proposed low-power FSK demodulation circuits further improve energy of demodulation. The implemented with 180nm CMOS process occupies an area 0.836mm2. post-layout simulation results show that overall PTE (including resonant tanks rectifier) SWPDT can be up 76.5% 40mW load. Meanwhile, 1.11Mbps achieved. consumption $69.1~\mu \text{W}$ , showing 62.2pJ/bit. shows potential implantable biomedical applications.

Discrete Rate Scheduling for Power Efficient Transmission over Wireless Link
While scheduling transmissions in a wireless communications system can result in significant power savings, a realistic scheduling scheme must take into acvount practical constraints that apply to wireless transmitters. Here, we examine scheduling actions for power efficiency under the constraints that physical transmission may be carried out at a set of fixed non-zero rates. For this class of ...
متن کاملEnergy-Efficient Packet Transmission Over a Wireless Link
The paper considers the problem of minimizing the energy used to transmit packets over a wireless link via lazy schedules that judiciously vary packet transmission times. The problem is motivated by the following observation. With many channel coding schemes, the energy required to transmit a packet can be significantly reduced by lowering transmission power and code rate, and therefore transmi...
متن کاملA Magnetic-Balanced Inductive Link for the Simultaneous Uplink Data and Power Telemetry
When using the conventional two-coil inductive link for the simultaneous wireless power and data transmissions in implantable biomedical sensor devices, the strong power carrier could overwhelm the uplink data signal and even saturate the external uplink receiver. To address this problem, we propose a new magnetic-balanced inductive link for our implantable glaucoma treatment device. In this in...
