本文介绍了可配置的 3.6 至 7.5 GHz 脉冲 UWB 发射器 IC，适用于具有高数据速率要求的神经植入物。 RF 脉冲的每个周期的幅度和持续时间均可进行数字编程，从而能够非常灵活地对传输的 PSD 信号进行整形，而无需使用输出滤波器。当从电源汲取 8.5 pJ/bit 的能量和 13 µW 的恒定静态功率时，发射器可实现最高 34% 的能效。该发射器采用 65nm CMOS 实现，尺寸为 1.0 mm × 0.7 mm。还报道了使用该芯片的32通道录音实验。
This paper describes configurable, 3.6 to 7.5 GHz pulse UWB transmitter IC targeted for neurological implants with high data rate requirements. Each cycle of the RF pulse is digitally programmable in amplitude and duration, enabling a very flexible shaping of the transmitted PSD signal, without the use of an output filter. The transmitter achieves a maximum of 34% of energy efficiency when drawing 8.5 pJ/bit from the supply, with 13 µW of constant static power. This transmitter was implemented in 65nm CMOS and measures 1.0 mm × 0.7 mm. A 32-channel recording experiment using this chip is also reported.
