A TERMINATION NETWORK AND A CONTROL CIRCUIT |
摘要 |
A termination network in an integrated circuit, and a control circuit for controlling the impedance of the termination network is described. The termination network comprises transistors for matching the impedance of the termination network with the characteristic impedance of a transmission line, which is connected to the termination network. The control circuit comprises a reference transistor which is integrated on the same integrated circuit as the termination network. The control circuit senses the impedance of the reference transistor and controls the reference transistor and the transistors in the termination network in such a way that the impedance is not affected by variations in temperature and in the manufacturing process of the integrated circuit. |
