  • Patent number: 7843281
    Abstract: A circuit topology for multiple loads is provided. In an embodiment, the circuit topology includes a driving terminal (50), a first node (A), a first receiving terminal (10), and a second receiving terminal (20). The driving terminal is coupled to the first node via a main transmission line (11), the first node is respectively coupled to the first and second receiving terminals via a first branch transmission line (13) and a second branch transmission line (12). A first resistor (R2) is mounted on the second branch transmission line, a distance the signal travels from the driving terminal to the second receiving terminal via the main transmission line and the second branch transmission line is greater than a distance the signal travels from the driving terminal to the first receiving terminal via the main transmission and the first branch transmission line.

  • Patent number: 7746195
    Abstract: A circuit topology for multiple loads includes a driving terminal, a first node coupled to the driving terminal and a second node via a first branch transmission line, a first receiving terminal which is a test point configured to detect errors of the circuit topology coupled to the first node via a second branch transmission line, a second and a third receiving terminal respectively coupled to the second node via a third branch transmission line and a fourth branch transmission line, wherein the difference between the length of the second branch transmitting line and that of the third branch transmitting line, and the difference between the length of the third branch transmitting line and that of the fourth branch transmitting line are greater than the product of a transmission speed and a rise time of the signal, and a first resistor is connected in the third branch transmission line.
