Abstract
A multivibrator circuit employing field effect transistors which operates with a high oscillation frequency and low power consumption comprises four series connections. The first series connection comprises a parallel connection including a resistor R.sub.1 and a diode D.sub.1 connected in parallel, and two field effect transistors Q.sub.1 and Q.sub.3, the first series connection being provided between the power supply V.sub.DD1 and the ground V.sub.SS. The second series connection comprises a field effect transistor Q.sub.5, diodes D.sub.3 for shifting a level and a field effect transistor Q.sub.7, the second series connection being provided between the power supply V.sub.DD2 and the ground V.sub.SS. The third series connection comprises R.sub.2, a diode D.sub.2 and two field effect transistors Q.sub.2 and Q.sub.4 in the same manner as in the first series connection. The fourth series connection comprises a field effect device Q.sub.6, diodes D.sub.4 for shifting a level and a field effect device Q.sub.8 in the same manner as in the second series connection. The first and second outputs are connected to the second and fourth series connections, respectively. A capacitor C.sub.1 is connected between the sources of the field effect transistors Q.sub.1 and Q.sub.2.
