ABSTRACT:
A pin electronics card including a connector connected to a test board on which an objective device is mounted; a signal processing circuit connected to the connector, for receiving an output signal from the objective device; and a ringing preventive circuit connected between the signal processing circuit and the connector, for removing ringing on the output signal. The ringing preventive circuit includes a buffer amplifier having an input terminal connected to the connector, and an output terminal connected to the signal processing circuit, a first comparator having a first input terminal connected to the output terminal of the buffer amplifier, a second input terminal provided with a first reference voltage, and an output terminal, for outputting a control signal from the output terminal in response to a result of comparison between voltages of the first and second input terminals, and a first current supply circuit having a first terminal connected to a power source for supplying a supply voltage, a second terminal connected to the input terminal of the buffer amplifier, and a control signal input terminal connected to the output terminal of the first comparator, for controlling conduction and non-conduction of a current flowing from the first terminal to the second terminal of the first current supply circuit in response to the control signal.
