ABSTRACT:
An integrated circuit sense amplifier includes a pair of complementary inputs for receiving a pair of complementary data signals which are input to a CMOS flip-flop having its output nodes connected to a logic low through a first transistor and its high side connected to a logic high through a second transistor. The first transistor is on when data signals are not being sensed, holding the nodes in a no-current, logic low state. The first transistor turns off and the second transistor turns on just prior to the arrival of a signal, precharging the nodes to an intermediate voltage, permitting the flip-flop to latch more quickly to a full-logic output when the signal arrives. A preamp may be interposed between the complementary inputs and the latch. The preamp inputs and outputs are precharged to voltage levels near or between their anticipated final levels, so that they reach their final levels quickly when the data signal arrives. The flip-flop output nodes may be connected to a tristate output circuit, which is also precharged to an intermediate level, enabling it to reach its full output more quickly.
