摘　　要：在可植入式生物电子设备中,无线数据传输模块是内部设备和外部设备之间进行数据交互的重要模块。有限的电池体积和植入安全性要求传输功耗尽可能低。基于幅度移键控(ASK)和开关键控(OOK)的调制解调方案,架构简单、功耗低以及便于植入,因而被广泛采用。文章提出了一种低功耗的双向无线数据传输电路,进行了电路设计及仿真。仿真结果表明,在XFAB 0.18μm工艺下,当最小调制深度为3.2%、最小输入为1.76 V时,正向传输数据率达到1 Mbit/s,实现了120 pJ/bit的能效,反向传输数据率达到500 kbit/s,实现了532.3 pJ/bit的能效。In implantable bioelectronic devices, wireless data telemetry module was an important module for data interaction between internal and external devices. The limited battery size of the device and implantation safety required minimizing the power consumption of transmission. Amplitude shift keying(ASK) and On-off keying(OOK)-based modulation and demodulation scheme was widely used because it has simple architecture, low power consumption, and easy to implant. A low power bidirectional wireless data telemetry module was proposed in this paper, and the circuit design and simulation were carried out. The simulation results showed that in the XFAB 0.18 μm process, when the minimum modulation depth was 3.2% and the minimum input was 1.76 V, the forward transmission data rate reached 1 Mbit/s, achieving 120 pJ/bit energy efficiency, and the reverse transmission data rate reached 500 kbit/s, achieving 532.3 pJ/bit energy efficiency.
