Abstract
In a high frequency oscillator circuit including first and second field effect transistors, the first field effect transistor has a gate connected to a short-stub transmission line and a drain connected to an oscillation output terminal, and the second field effect transistor has a drain connected to a source of the first field effect transistor and a grounded source. The high frequency oscillator circuit oscillates by using a feedback circuit including the short-stub transmission line and the second field effect transistor. A feedback capacitor is further provided which is connected between a gate of the second field effect transistor and the drain of the first field effect transistor.
