This paper points out that: (1) an electron-coupled oscillator has a sluggish loop characteristic with respect to supply voltage, (2) the most commonly used electron-coupled oscillator circuit is an incomplete electron-coupling circuit and has rather poor frequency characteristics, (3) the frequency stability can be greatly improved by applying phase compensation, (4) the best e.c.o. circuit is a modified Colpitts oscillator with grounded cathode.
