Abstract: The invention relates to an oscillator OSC intended to provide an output signal having a frequency which is variable as a function of a tuning voltage Vtun. The oscillator OSC includes a passive part having two series-arranged variable capacitances Cs, biased by the tuning voltage Vtun, and connected to a power supply VCC via two inductances Lext, and an active part having a first transistor T1 and a second transistor T2 whose collectors are connected to the output terminals C1 and C2 of the passive part, the base of one transistor being connected to the collector of the other transistor via a coupling capacitor Cfb. According to the invention, the passive part includes two high-pass filters, each being inserted between one of the output terminals S1 or S2 and one of the variable capacitances Cs, which allows a reduction of the active part's sensitivity to low-frequency noise.

Abstract: Phase shifter to which are applied two signals in a phase opposition (v, -v) is constituted by a first series circuit of a resistor and a capacitor (R.sub.1, C.sub.1), and a second series circuit of a resistor and a capacitor (R.sub.2, C.sub.2). So that neither the relative amplitudes nor the relative phases of all the signals used at the outputs (5, 6, 7, 8) are degraded by the impedance of the stages that follow, the phase shifter includes a first network of a resistor and a capacitor connected in parallel (C.sub.3, R.sub.3), and a second network of a resistor and a capacitor connected in parallel (C.sub.4, R.sub.4). Both the four resistors and the four capacitors of the phase shifter are each substantially equal in value.
