Abstract (in Japanese) (See Japanese page) 
(in English) The detecting circuit of Electron Spin Resonance (ESR) for radical sensing and the detection sensitivity analysis of ESR signal are presented. The circuit is composed of probe-inductor for ESR measurement and cascode Low Noise Amplifier (LNA) which improves the detection sensitivity of ESR signal. ESR signal is obtained as a spectrum of the gain variation of the LNA as a function of the DC magnetic flux. As the result of circuit simulation, the detection sensitivity of ESR signal by the designed circuit is estimated at 90×10-3fV/spin@RFin=-50dBm. It is possible to detect radicals included in a very small amount of sample with the proposed circuit which contributed to downsizing the ESR measurement system.
