Abstract
A driver with the arrangement of the travelling wave amplifier is disclosed. The driver provides n counts of cells each configuring the open collector arrangement and amplifying an input signal. The cells are arranged between an input interconnection and an output interconnection, and powered through the output interconnection. The power supply line to power the output interconnection is connected between m-th and (m+1)-th cells not through the output terminal of the output interconnection.
