我们已经实现了一种创新的电子自旋共振光谱集成探测器。该微系统由 LC 振荡器、混频器和分频模块组成，采用传统的互补金属氧化物半导体技术集成到单个硅芯片上。所实现的检测方法基于对集成 LC 振荡器的频率变化的测量，该变化是由于放置在 LC 储能电路的电感器上的谐振样本的存在而引起的，该变化是所施加的静磁场的函数。所达到的室温自旋灵敏度约为 10(10) spinsGHz(12)，敏感体积约为 (100 微米)(3)。
We have realized an innovative integrated detector for electron spin resonance spectroscopy. The microsystem, consisting of an LC oscillator, a mixer, and a frequency division module, is integrated onto a single silicon chip using a conventional complementary metal-oxide-semiconductor technology. The implemented detection method is based on the measurement of the variation of the frequency of the integrated LC oscillator as a function of the applied static magnetic field, caused by the presence of a resonating sample placed over the inductor of the LC-tank circuit. The achieved room temperature spin sensitivity is about 10(10) spinsGHz(12) with a sensitive volume of about (100 microm)(3).
