Patent ID: 6995624

Claim:
Oscillator circuit comprising: an LC resonant circuit ( 1 ), an activating component ( 2 ) connected to the LC resonant circuit ( 1 ), which serves to compensate for the losses occurring in the LC resonant circuit ( 1 ), whereby the series-configuration of both the LC resonant circuit ( 1 ) and the activating component ( 2 ), a current-defining element which connects the LC resonant circuit and the activating component, which sets the current flowing through the activating component ( 2 ), between a first voltage (VDD) and a second voltage (VSS), which is different from the first voltage (VDD), and wherein the current-defining element includes an ohmic resistance (R 1 ) and wherein the oscillator circuit furthermore comprises a control loop circuit, which serves to set the current flowing through the activating component ( 2 ) to a pre-determined constant value, wherein the control loop circuit comprises a copy ( 3 ) of the activating component.
