Integrated circuit

   
   

In an integrated circuit, a time-axis expanding circuit is provided in addition to a driver circuit for outputting a signal outside. The time-axis expanding circuit has an equivalent receiver circuit similar to an ordinary receiver circuit, and a D-type flip-flop circuit connected to the equivalent receiver circuit. Input signals from the pins of the time-axis expanding circuit are inputted to the gates of CMOS transistors of the equivalent receiver circuit, and equivalent differential receiving signals outputted from the drains of the CMOS transistors are inputted to the D input terminal of the D-type flip-flop circuit. A measuring clock signal is inputted to the clock input terminal of the D-type flip-flop circuit, and a time-axis-expanded signal is outputted from the Q output terminal of the D-type flip-flop circuit to an output terminal of the time-axis expanding circuit.

Em um circuito integrado, um circuito de expansão da tempo-linha central é fornecido além a um circuito do excitador outputting um sinal fora. O circuito de expansão da tempo-linha central tem um circuito equivalente do receptor similar a um circuito ordinário do receptor, e um D-tipo circuito de flip-flop conectado ao circuito equivalente do receptor. Os sinais de entrada dos pinos do circuito de expansão da tempo-linha central inputted às portas de transistor do CMOS do circuito equivalente do receptor, e o diferencial equivalente que recebe sinais outputted dos drenos dos transistor do CMOS inputted ao terminal da entrada de D do D-tipo circuito de flip-flop. Um sinal de medição do pulso de disparo inputted ao terminal da entrada de pulso de disparo do D-tipo circuito de flip-flop, e um sinal tempo-linha-expandido é outputted do terminal de saída de Q do D-tipo circuito de flip-flop a um terminal de saída do circuito de expansão da tempo-linha central.
