This article presents a selection of the calculated and measured results of an oscillator circuit using two source‐coupled junction field‐effect transistors (JFETs), which are investigated at a number of different operating points. These results illustrate vividly some strange but typical problems of the oscillator design, such as “spurious” and “wrong” or “jumping” oscillation frequency. © 2004 Wiley Periodicals, Inc.
