Abstract
An amplitude control inverter circuit for an electronic device having a power source and a signal source. A complementary pair of field effect transistors having gate electrodes are connected to the signal source, and at least one amplitude control field effect transistor is connected to the complementary pair of field effect transistors. The amplitude control field effect transistor has its gate electrode responsive to a phase delayed output of the complementary pair of field effect transistors to control a duration of current flow in the complementary pair of field effect transistors. A resistor is connected to the gate electrode of the amplitude control field effect transistor. A capacitor has one terminal connected to a terminal of the resistor and also to the amplitude control field effect transistor, and another terminal connected to the power source. The amplitude control inverter circuit may be used in crystal oscillators and in buffer amplifiers.
