Abstract:
1. A driver circuit for outputting a simulated signal simulating an input signal subjected to transmission loss, corresponding to said input signal, the driver circuit comprising: a main driver which receives said input signal and outputs a first signal corresponding to said input signal; a sub driver which receives said input signal and outputs a second signal by inverting said input signal where said sub driver is a differential driver which further outputs a fourth signal corresponding to said input signal; a high frequency emphasizing circuit which receives said second signal and outputs a third signal having the high frequency of said second signal emphasized; an addition unit which outputs said simulated signal by adding said first signal to said third signal; and an additional high frequency emphasizing circuit which receives said fourth signal and outputs a fifth signal having the high frequency of said fourth signal emphasized; and wherein said addition unit outputs a signal by adding said fifth signal to said simulated signal or said first signal.
