摘要

采用0.13μm SiGe BiCMOS技术实现了时域EPR光谱集成收发器。该系统利用片上谐振器来研究顺磁性样品的时域弛豫行为，即具有不成对电子自旋的材料。单片EPR光谱仪由一个EPR谐振器、22-26GHz可调谐压控振荡器、一个可编程脉冲产生模块、RF缓冲器和功率放大器、一个多级LNA和下变频混频器组成，所有这些都在一个2mm2大小的芯片区域中。

A silicon-based, fully integrated pulse electron paramagnetic resonance system for mm-wave spectroscopy

An integrated transceiver for time-domain EPR spectroscopy is implemented using a 0.13μm SiGe BiCMOS technology. The system utilizes an on-chip resonator to study time domain relaxation behavior of paramagnetic samples, i.e. materials with unpaired electron spins. The single-chip EPR spectrometer consists of an EPR resonator, 22-26GHz tunable VCO, a programmable pulse generation block, RF buffer and power amplifier, a multi-stage LNA, and down-conversion mixer all in a 2mm2-size chip area.
