Abstract

In one aspect the present invention relates to an electronic circuit (100) comprising: - a chain (12) of buffers (40, 40', 40"), wherein each buffer (40) comprises a buffer input (45), a buffer output (46), a buffer current source (44) and a buffer capacitor (43) and wherein a transition time of each buffer (40, 40', 40") is controllable by the buffer current source (44, 44', 44"), - an oscillator (70, 71, 72) configured to generate an oscillating reference signal, and - a control circuit (80) coupled to the oscillator (70, 71, 72) and coupled to the buffer current sources (44, 44', 44") of the buffers (40, 40', 40") and operable to adjust the transition time of each buffer (40, 40', 40") on the basis of the oscillating reference signal.
