An Improved Latching Pulse Design For Dynamic Sense Amplifiers

A generalized optimal latching pulse for dynamic sense-amplifier design has been derived. The model equations account for threshold voltage imbalance, bit-line capacitance imbalance, current gain imbalance, gate capacitance and intra-bit-line capacitive coupling effect, channel-length modulation, source-body effect, and temperature sensitivity in a unified manner. Computer simulations of the analytical equations, including those effects, are presented. A design implementation for fast sense-amplifier operation is also presented to demonstrate the utility of the model equations for practical application. © 1990 IEE
