A Simple Circuit of a Crystal Oscillator and Its Application to a High-Resolution NMR Spectrometer.

摘要

A simple circuit of a crystal oscillator operating at frequencies from several megahertz to a hundred megahertz with a frequency stability of one part to 10 to the 8th power can be constructed by use of a dual insulated-gate metal-oxide-semiconductor field-effect transistor (MOSFET). This RF transmitter accompanied by an RF-tuned receiver can be used as a high-resolution NMR spectrometer and as a precise gaussmeter. (Author)
