A high-speed current-mode sense-amplifier for (CMOS SRAM's)

A new merged current-mode sense-amplifier engaging current conveyor for column sensing and current-mode CMOS cross-coupled latch as its global sense-amplifier is presented. The sensing speed of this circuit topology proves to be faster than that of the conventional current sense-amplifier. The new current sense-amplifier is insensitive to both bit-like and data-like capacitances. The sensing speed is twice as fast with the current consumption remaining the same, and voltage noise coupling is reduced.<
