ABSTRACT:
A C-MOS oscillator circuit having input and output terminals adapted to be connected to a resonator and two active MOS transistors of complementary types connected in series between the supply terminals of the circuit, which supply terminals are connected to the positive and negative poles of a source of d.c. voltage, the sources of the transistors being connected to a supply terminal and the drains being connected to the output terminal. The d.c. bias and the a.c. voltage control of each of the active transistors are ensured by a MOS transistor of the same type connected as a diode between its gate and its drain, a current source connected between its gate and the supply terminal to which the source of the other active transistor is connected, and a capacitive voltage divider which is connected between the supply terminal, to which its source is connected, and the input terminal, and the intermediate point of which is connected to its gate.
