Abstract
Abstract An electronic system includes a plurality of electronic circuits each having a signal input and output function, a bus to which the plurality of electronic circuits are connected, first termination resistors connected to ends of the bus, and a termination voltage circuit having a first part generating a first voltage and a second part generating a second voltage. The sum of the first voltage and the second voltage is supplied, as a power supply voltage, to output circuits of the plurality of electronic circuits connected to the bus. The second voltage is supplied to the first termination resistors as a termination voltage.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
140 words
An electronic system comprising: a plurality of electronic circuits having a signal input and ouput function and a push-pull type output circuit; a bus to which the plurality of electronic circuits are connected; and a termination device having a first non-linear element, and a second non-linear element, the first non-linear element being connected between a termination voltage line and said bus in a forward direction, the second non-linear element being connected, in the foreward direction, between the bus and a voltage line carrying a voltage lower than a termination voltage supplied via the termination voltage line, wherein: said first and second non-linear elements are diodes; and a sum of forward direction threshold voltages of the first and second non-linear elements are greater than a difference between the termination voltage carried via the voltage line and lower than the termination voltage.
