An Incremental Phase Shifter and Frequency Modulator for Magnetic Resonance Imaging and Spectroscopy

Abstract

A digitally controlled analog phase shifter is described for the application in magnetic resonance (MR) imaging and spectroscopy. The design is based on a single side band modulator scheme. A phase resolution of 1.4°and a switching time of 400 ns are achieved. The device controls the phase of the intermediate frequency in the MR instrument, and hence can be… (More)
