Abstract
A novel sense amplifier is taught which minimizes power consumption by causing selected current sources to conduct current only when an input signal of a selected state is present. The speed of the circuit is fast because capacitance on the critical nodes is minimized by connection of fewer transistors to the critical nodes, as compared with the prior art.
