摘要： A driver circuit transmits a signal generated by a signal level generation circuit to a circuit to be measured by transmitting the signal to a output buffer circuit via a circuit (prebuffer circuit) that drives the output buffer circuit and causing the output buffer circuit to drive a transmission line. The driver circuit includes the prebuffer circuit and a replica buffer circuit formed by imitating the prebuffer circuit. The prebuffer circuit and the replica buffer circuit are disposed in parallel. The driver circuit temporarily increases input bias current to be supplied to output-stage transistors of the output buffer circuit on the basis of output current of the replica buffer circuit during transition of an input or output signal.
