Abstract
A two stage input buffer substantially reduces propagation delay by triggering only off of the rising edge of the external clock signal, eliminating a pulse generator, and setting the pulse width via feedback through a fixed delay. An unbalanced driver reduces capacitance on the N-channel transistor. In a memory application, such as in a synchronous dynamic random access memory, access time is improved, margin is advantageously added to the hold time requirement, and driver fan out capabilities are improved.
