The circuit (1) has an inverter composed of positive and negative complementary Metal Oxide Semiconductor transistors (P1, N1) mounted in series with a biasing current source (4) between a positive terminal (VDD) and a ground terminal of a continuous supply voltage source to define an active branch. An operational transconductance amplifier (2) is arranged between drain and grid terminals of the inverter transistors, where the amplifier has a high impedance value not to degrade transconductance of the branch for generating oscillation at level of a clock quartz (3). |
