A circuit for producing a reference current has a capacitor (2) connected to a voltage-controlled current source input (1) which is controlled by two selectable (8) amplifiers (4,6) of differing drive capabilities (gm1,gm2). An LC-oscillator (14) can thus be current-controlled and fed with noise-reduced reference current. An Independent claim is also included for an oscillating circuit comprising the above. |
