M. Nogawa et al., A LOW-POWER AND HIGH-SPEED IMPULSE-TRANSMISSION CMOS INTERFACE CIRCUIT, IEICE transactions on electronics, E78C(12), 1995, pp. 1733-1737
A new low-power and high-speed CMOS interface circuit is proposed in w
hich signals are transmitted by means of impulse voltage. This mode of
transmission is called impulse transmission. Although a termination r
esistor is used for impedance matching, the current through the output
transistors and the termination resistor flows only in transient stat
es and no current flows in stable states. The output buffer and the te
rmination resistor dissipate power only in transient states, so their
power dissipation is reduced to 30% that of conventional low-voltage-s
wing CMOS interface circuits at 160 MHz. The circuit was fabricated by
0.5 mu m CMOS technology and was evaluated at a supply voltage of 3.3
V. Experimental results confirm low power of 4.8 mW at 160 MHz and hi
gh-speed 870 Mb/s error free point-to-point transmission.
