ABSTRACT:
An oscillator includes a resonant circuit of at least one inductance device and at least one tunable capacitance. The tunable capacitance is implemented through diffusion capacitances of at least one current-carrying transistor. The tunable capacitance has a first differential amplifier having a first transistor and a second transistor and a second differential amplifier having a third transistor and a fourth transistor Electrical properties of the first transistor and second transistor are complementary to electrical properties of the third transistor and fourth transistor, and control connections of the first transistor and the third transistor are connected to one another. Control connections of the second transistor and the fourth transistor are connected to one another. Second current connections of the first transistor and the third transistor are connected to one another, and second current connections of the second transistor and the fourth transistor are connected to one another.
