A single ended current sensed bus with novel static power free receiver circuit is described herein. In one embodiment, a receiver circuit example includes a latch circuit to latch values for a first output and a second output during an evaluation phase in response to an input, a pre-charge circuit coupled to the latch circuit to pre-charge the latch circuit during a pre-charge phase, and a static power dissipation blocking (SPDB) circuit coupled to the pre-charge circuit and the latch circuit to substantially block static power from being dissipated during the pre-charge phase. Other methods and apparatuses are also described.

A clock receiver circuit converts low amplitude, differential clock signal components received from a differential clock distribution medium into a full swing digital clock. The clock receiver circuit can be used as part of, for example, an on-die salphasic clock distribution system within a microelectronic device.

A hierarchical clock distribution system includes a global clock grid that distributes a clock signal to a plurality of regional clock grids. Each of the regional clock grids then distributes the signal to a plurality of corresponding loads. The regional clock grids utilize salphasic clocking techniques to distribute the clock signal to the corresponding loads. The global grid achieves low skew based on the periodicity of the clock signal, rather than the dominance of a standing wave. The electrical distance to termination within the regional clock grids is preferably kept low to avoid the occurrence of phase change regions on the regional grids. In one approach, the regional grids are each driven at multiple points in a symmetrical fashion to reduce the electrical distance to termination.

A voltage level converter includes a static voltage level converter and a split-level output circuit coupled to the static voltage-level converter. In another embodiment, the voltage-level converter includes a static voltage level-converter, a first transistor, and a second transistor. The static voltage-level converter includes an input node, a first pull-up node, a second pull-up node, an inverter output node, and an output node. The first transistor is coupled to the input node and the first pull-up node. The second transistor is coupled to the second pull-up node and the inverter output node.

A sense amplifier transition encodes an output signal onto a bus such that the bus signal only transitions when a sensed bit line has a state different from the state of a previously sensed bit line. The sense amplifier includes a storage element that changes state when the bus signal is asserted. The output of the sense amplifier is conditionally inverted based on the state of the storage element.

A low loss on-die interconnect structure includes first and second differential signal lines on one of the metal layers of a microelectronic die. One or more traces may also be provided on another metal layer of the die that are non-parallel (e.g., orthogonal) to the differential signal lines. Because the traces are non-parallel, they provide a relatively high impedance return path for signals on the differential signal lines. Thus, a signal return path through the opposite differential line predominates for the signals on the differential lines. In one application, the low loss interconnect structure is used within an on-die salphasic clock distribution network.
