Abstract
In some embodiments, the invention includes a reference-free single ended sense amplifier. The sense amplifier includes first and second transistors in a differential pair, the first transistor having a control terminal connected to an input conductor to receive an intermediate signal, the first transistor having a data terminal connected to a node, and the second transistor having a control terminal coupled to the node. The sense amplifier further includes a cross-coupled inverter latch having a first inverter coupled to the first transistor through the node and a second inverter coupled to the second transistor. In some embodiments, the control terminal of the second transistor is tied to the node. The first and second transistors of the differential pair may be pFET transistors or nFET transistors or a combination of them. In some embodiments, the sense amplifier is includes as a part of a domino logic gate. Other embodiments are described and claimed.
