Abstract: A first pull-up transistor has a gate coupled to a clock signal line and a drain coupled to both a first pull-down transistor and a voltage clamp. A second pull-up transistor has a gate that is also coupled to the clock signal line and a drain coupled to both a second pull-down transistor and a voltage clamp. A shared pull-up transistor has a gate that is also coupled to the clock signal line and a drain coupled to both the first and second pull-down transistors. The shared pull-up transistor may be used to precharge an output node of the circuit. This circuit may be found useful in clock buffering applications.

Abstract: A technique for reducing power consumption in a data storage device consisting of a number of data cells includes arranging the number of data cells in clusters, each cluster having more than one data cell having their data enable inputs connected together. A data write bus is provided to provide data enable signals to the data enable inputs of the number of data cells. A number of pass gates are respectively disposed between the clusters and the write data bus. The pass gates are selectively enabled to allow data enable signals to pass from the write data bus to the data enable inputs of the more than one data cell of a selected one or more of the clusters. A number of inverters may be respectively disposed between the number of pass gates and the clusters. A number of sustainer circuits may be respectively connected to the number of pass gates. Each of the pass gates may include a pair of field effect transistors which may be complementary field effect transistors.

Abstract: A clock buffer includes a clocked pull-up transistor and a clocked pull-down transistor. The clocked pull-up transistor has a drain coupled to an output line and a gate coupled to a clock signal line. The clocked pull-down transistor includes a drain coupled to the output line, a gate coupled to the clock signal line, and having a width Y. The buffer further includes a first pull-down transistor having a drain coupled to a source of the clocked pull-down transistor, a gate coupled to a first input signal line, and having a width that is at least 10% greater than Y. This clock buffer provides reduced power consumption in comparison to a more conventional clock buffer.

Abstract: A circuit includes first and second pull-up transistors having first and second drains, respectively, each coupled to separate voltage clamps. The gates of each of the two pull-up transistors are coupled to a clock signal line. The circuit further includes a shared pull-down transistor, the gate of which is coupled to the clock signal line. The drain of the shared pull-down transistor is coupled to the first drain via at least one pull-down transistor in series with the shared pull-down transistor. The drain of the shared pull-down transistor is also coupled to the second drain via at least one pull-down transistor in series with the shared pull-down transistor. This circuit may be found useful in multiplexing applications.
