總結: | A full current-mode sense amplifier is presented. It
extensively utilizes the cross-coupled inverters for both local and
global sensing stages, hence achieving ultra low-power and ultra
high-speed properties simultaneously. Its sensing delay and
power consumption are almost independent of the bit- and dataline
capacitances. Extensive pre-layout simulation results based
on a 1.8 V/0.18 μm CMOS technology from Chartered
Semiconductor Manufacturing Ltd. (CHRT) have verified that
the new SA outperforms the best published designs with 64% and
45% speed and power consumption improvements respectively.
Furthermore, the new design can operate down to a supply
voltage of 1 V. These attributes of the proposed SA make it
judiciously appropriate for the use in the contemporary highcomplexity
systems, which continually crave for low-power and
high-speed characteristics. |
