Disclosed is a circuit system generating a reference current (Iref) and an oscillator circuit which comprises said circuit system and a capacitor (8) that is connected to the input of a voltage-controlled source of electric power (1). Said capacitor (8) is triggered by two inter-switchable amplifiers (4, 6) with different driving capacities (gm1, gm2). According to said principle, an LC oscillator (14), for example, can be electrically controlled while being fed with the reference current (Iref) at a particularly low noise level. |
