我们报告了第一个基于吸收的单芯片收发器的电子顺磁共振（EPR）光谱在硅。该芯片采用0.13 μ mSiGe BiCMOS工艺技术实现。发射机产生并发送频率范围为895至979 MHz的连续波微波信号，接收机采用直接变频架构。基于单片收发器和基于印刷电路板的平面谐振器，组装并测试了EPR谱仪。该光谱仪成功地测量了样品的EPR响应，包括2，2-二苯基-1-苦肼粉末，Fe 3 O 4纳米颗粒和Fe 2 O3纳米颗粒。
We report the first absorption-based single-chip transceiver for electron paramagnetic resonance (EPR) spectroscopy in silicon. The chip is implemented in a 0.13-μm SiGe BiCMOS process technology. The transmitter generates and delivers a continuous-wave microwave signal with a frequency range from 895 to 979 MHz and the receiver adopts a direct-conversion architecture. Based on the single-chip transceiver and a printed-circuit-board-based planar resonator, an EPR spectrometer is assembled and tested. The spectrometer successfully measures the EPR response from samples including 2,2-Diphenyl-1-Picrylhydrazyl powder, Fe3O4 nanoparticles, and Fe2O3 nanoparticles.
