Abstract
A magnetic resonance (MR) receiver is described herein. The MR receiver can be used to process nuclear magnetic resonance (NMR) signals. The MR receiver includes a transformer that amplifies the MR signals and a preamplifier that receives the MR signals from the transformer. The preamplifier can include a transimpedance amplifier circuit with an input stage that includes a field effect transistor.
