  • Publication number: 20090261880
    Abstract: In order to transfer data at high speed over a long distance, a current mode logic output circuit (CML) having a large number of taps, high accuracy, and a wide switchable range of the amount of pre-emphasis is needed. However, when the amount of emphasis is set by adding unit source-coupled pair circuits, a problem will arise that the output capacitance of the current mode logic output circuit would increase, thus hampering high-speed transmission. An output circuit of the invention is constructed from unit source-coupled pair circuits 501, which are obtained by dividing a current mode logic output circuit (CML) into m groups, terminal resistors 502, and a data selector 504. The amount of emphasis of each tap is determined by the ratio of the number of unit source-coupled pair circuits, which have been obtained by dividing the CML into m groups, allocated to each tap. Thus, the amount of emphasis can be set to be any arbitrary amount without a change in the output amplitude of 1.

  • Publication number: 20030074412
    Abstract: An electronic mail communication system comprises a base station 1 and at least one portable terminal 2. A mail server 3 of the base station 1 transmits only the header portion of the electronic mail to the portable terminal 2. The portable terminal 2 receiving the header portion compares the transmitter mail address extracted from the header portion with reception target mail addresses registered in the portable terminal 2 in advance by the user. If the transmitter mail address is coincident with one of the registered reception target mail addresses, the portable terminal 2 requests the mail server 3 to transmit the mail body of the electronic mail, and if the transmitter mail address is not coincident with any registered reception target mail address, the portable terminal 2 requests the mail server 3 to delete the mail body.
