Robinson oscillator

The Robinson oscillator (or Robinson marginal oscillator) is an electronic circuit used in the field of Nuclear Magnetic Resonance (NMR). The oscillator forms the underlying basis of Magnetic Resonance Imaging (MRI) systems used in many hospitals. It was invented by the British physicist Neville Robinson.
