论文摘要
我们提出了一个宽带宽度，电压控制的电流源的设计，该电源很容易与射频磁场线圈集成。我们的设计使用当前的反馈来补偿射频天线的频率依赖性阻抗。我们能够在300 kHz至54 MHz频率范围内传递大于100 mA的峰值电流。射频电流源拟合到小于$ 4〜 \ text {cm}^2 $的印刷电路板上，并且消耗的功率小于1.3 W。它适用于可部署的量子传感器和核磁复合系统。
We present a design for a wide-bandwidth, voltage-controlled current source that is easily integrated with radiofrequency magnetic field coils. Our design uses current feedback to compensate for the frequency-dependent impedance of a radiofrequency antenna. We are able to deliver peak currents greater than 100 mA over a 300 kHz to 54 MHz frequency span. The radiofrequency current source fits onto a printed circuit board smaller than $4~\text{cm}^2$ and consumes less than 1.3 W of power. It is suitable for use in deployable quantum sensors and nuclear-magnetic-resonance systems.
