Abstract: Provided is a microstrip transmission line for reducing far-end crosstalk. In a conventional microstrip transmission line on a printed circuit board, a capacitive coupling between adjacent signal lines is smaller than an inductive coupling therebetween, so that far-end crosstalk occurs. According to the present invention, the capacitive coupling between the adjacent signal lines is increased to reduce the far-end crosstalk. A vertical-stub type microstrip transmission line is provided.

Abstract: A current-mode bidirectional input/output buffer circuit for impedance matching and operation at a high speed. The current-mode bidirectional input/output buffer circuit communicates with an external chip having the same current-mode bidirectional input/output buffer. In the buffer, a transmitting-receiving average voltage output unit converts an average current value between a transmission signal to be transmitted to the external chip and a receiving signal transmitted from the external chip, into an average voltage. A reference voltage output unit converts a reference current value selectively generated according to a voltage level of the transmission signal, into a reference voltage. A comparator compares the voltage from the transmitting-receiving average voltage output unit to the voltage from the reference voltage output unit to provide a logic signal corresponding to the received signal transmitted from the external chip. A bias voltage generator generates a bias voltage such that the impedance of each output unit is matched with a characteristic impedance of a transmission line coupled to the external chip, and provides the bias voltage to the transmitting-receiving average voltage output unit and the reference voltage output unit. Accordingly, the current-mode bidirectional input/output buffer transmits data between chips at a high rate using a single transmission line and is stable in spite of variations in processes for fabricating chips.

Abstract: A bidirectional input/output buffer operates in a current mode to increase the data transfer rate between devices connected by a bidirectional transmission line. The buffer includes an output current source for generating an output current responsive to a data output signal. The output current is combined with an output current indicative of a data input signal received from another device over a transmission line, thereby forming a mixed current signal. The data input signal is restored from the mixed signal by a restoring circuit that compares the mixed signal to a reference current that depends on the value of the data output signal. The restoring circuit includes a current mirror and a reference current source that generates a reference current in response to the data output signal. To provide additional performance, an embodiment of a bidirectional input/output buffer utilizes a switchless structure having two comparators that compare the mixed signal to two different reference signals, thereby generating two comparison signals. A selector circuit selects one of the two comparison signals as the restored data input signal responsive to the data output signal.
