PROJECT TITLE :

A Single-Chip Electron Paramagnetic Resonance Transceiver in 0.13-$mu$ m SiGe BiCMOS

ABSTRACT:

We report the first absorption-based mostly single-chip transceiver for electron paramagnetic resonance (EPR) spectroscopy in silicon. The chip is implemented in an exceedingly zero.thirteen- m SiGe BiCMOS method technology. The transmitter generates and delivers an eternal-wave microwave signal with a frequency vary from 895 to 979 MHz and the receiver adopts a right away-conversion design. Primarily based on the one-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 two,a pair of-Diphenyl-one-Picrylhydrazyl powder, Fe O nanoparticles, and Fe O nanoparticles.
