提出了一种通过感应链路向生物医学可植入设备传输数据和功率的新技术。数据传输技术是基于改变E类功率放大器的开关脉冲的占空比。因此，我们称之为占空比移位键控（DCSK）。所提出的技术的调制器和解调器是简单的，并使其适用于生物植入式设备。数据速率与载波频率之比可以高达100%。采用0.18 µm CMOS工艺，利用ADS仿真器对电路进行了仿真。此外，为了验证所提出的技术的有效性，使用现成的组件实现了测试设置。
A novel technique for transferring data and power to biomedical implantable devices through an inductive link is presented. The data transfer technique is based on changing the duty cycle of the switching pulse of the class E power amplifier. Hence, we have called it Duty Cycle Shift Keying (DCSK). The modulator and demodulator of the proposed technique are simple and make it suitable for bio-implantable devices. The data rate to carrier frequency ratio can be as high as 100%. The proposed circuit is simulated by ADS simulator using the 0.18 µm CMOS technology. Moreover, in order to verify the effectiveness of the proposed technique, a test setup is implemented using off-the-shelf components.
