Abstract
A digital electronic device is provided with a first and second sequential logic unit (SS, SS), each for receiving an input signal (D) and for outputting a first and second output signal (Q, QF), respectively. The electronic device furthermore comprises a comparator unit (C) for comparing the first and second output signals (Q, QF) and an adaptive clock generator unit (ACG) for generating a first and second internal clock (CK, CKF) for the first and second sequential logic unit (SS, SS), respectively. In a self-tuning mode, the adaptive clock generator unit (ACG) is adapted to delay the first and second internal clock signals (CK, CKF) with respect to the other internal clock signal (CKF). The delay induced by the adaptive control generator unit (ACG) is dependent on the result of the comparison unit (C). In a normal operation mode the adaptive control generator unit (ACG) is adapted to maintain the delay between the first and second internal clock signals constant.
