Novel low-swing bus-drivers and charge-recycle architectures

In this paper novel single-rail low-swing bus-drivers based on schmitt-triggers as voltage level sensors are presented. Two novel 4-transistor schmitt-triggers with non-symmetrical trigger-voltage levels are also proposed. The power dissipation for the single rail low-swing bus-driver is reduced by 48 percent compared to a full-swing driver. Finally, two novel semi-adiabatic charge-recycle circuits are proposed. The power savings for these circuits are 45 and 65 percent, respectively. A data rate of 200 Mbit/s per driver has been reached in a double metal 0.8 μm process
