Beschreibung
Zusammenfassung:	The present invention relates to a differential ring oscillator stage, comprising differential delay means (Q1, Q2) having a first input (IN+) and an inverse second input (IN-) and a first output and an inverse second output, a first output buffer means (34a) having its input connected to the first output of said delay means (Q1, Q2), and a second output buffer means (34b) having its input connected to the second output of said delay means (Q1, Q2), and further comprising a first controllable current source means (M6) which is connected to the output (OUT+) of said first output buffer means (34a) and controlled in accordance with the signal from said second output of said delay means (Q1, Q2), and a second controllable current source means (M5) which is connected to the output (OUT-) of said second output buffer means (34b) and controlled in accordance with the signal from said first output of said delay means (Q1, Q2), said controllable current source means (M5, M6) supplying currents to the outputs (OUT+, OUT-) of said output buffer means (34a, 34b) such that within the working range the wave form of the currents is essentially proportional to the wave form of the signals from the outputs of said delay means (Q1, Q2).
