Abstract :
In this paper, a method for controlling the driving current is discussed and then an asymmetric emphasis technique that individually controls its waveform at the rising and falling edges is proposed. The circuit implementation for the asymmetric emphasis technique is discussed and experimental results for the fabricated test chip is provided.
