DRIVER CIRCUIT

摘要

A driver circuit (10) outputs, in response to an input signal, a simulated signal that simulates a signal having undergone a transmission loss and comprises a main driver (18), a sub-driver (20), a high frequency region enhancement circuit (22), and an adding circuit (24). The main driver (18) receives the input signal and outputs a signal having the same waveform as that of the input signal as an output signal. The sub-driver (20) receives the input signal and outputs a signal having the inverted waveform of the input signal as an output signal. The high frequency region enhancement circuit (22) receives the output signal of the sub-driver (20) and outputs a signal for enhancing the high frequency region of the output signal of the sub-driver (20) as an output signal. The adding circuit (24) outputs a simulated signal obtained by adding the output signal of the main driver (18) and the output signal of the high frequency region enhancement circuit (22).
