本文提出了一种基于注入锁定相位检测的超快扫描电子顺磁共振（EPR）芯片，工作频率14GHz，扫描速率达1400THz/s，可实现120µM浓度的顺磁物种检测。该芯片采用22nm FDSOI CMOS工艺，通过相干频率生成和信号下变频实现低噪声读出，无需锁相解调，单电感作为顺磁传感器。
span (100Gauss) Ultra-fast scan (1400THz/s) EPR-on-a-Chip based on injection-locked phase detection, implemented in CMOS 22nm-FDSOI technology is presented. 14GHz coherent frequency generation and sensing signal down-conversion is used to implement a stable and low noise EPR readout at around 500MHz without requiring lock-in based demodulation. A single inductor is used as paramagnetic sensor. The detection and direct analysis of paramagnetic species using Electron Paramagnetic Resonance (EPR) spectrometry is becoming a rapidly growing activity. Applications range from chemistry to biomedical and a wide range of materials characterization for energy production, quantum computing, semiconductors, etc. In EPR, two fields are applied to the
