Abstract: The digital electronic circuit (1) includes a logic cell (2) for processing data (82) , a flip-flop (3) for storing data (83) processed in the logic cell (2), a power supply (4), and a clock (5) for triggering the flip-flop (3) . The logic cell (2) is disconnected from the power supply (4) when the clock (5) is not active, as it is not needed for memorizing of the flip-flop states, and connected with the power supply (4) when the clock (5) is enabled. For switching the power supply, a switch (7) switched by the clock enable (6) is arranged between the logic cell (2) and the power supply (4). Such a simple additional switch (7) occupies only a relatively small area on the chip, but permits a drastic reduction by about 90% of the leakage currents. The circuit (1) is especially design and may be used for instance in mobile telecommunication devices.

Abstract: An integrated circuit has a clock input for receiving a primary clock signal, clock reconfiguring device fed by the clock input for generating one or more secondary reconfigured clock signals, and utility circuitry fed by the clock reconfiguring device for constituting application utility functions under synchronization by the secondary clock signals. In particular, the clock input a clock upscaling device for from the primary clock signal generating an intermediate clock signal with an upscaled frequency for thereby feeding the clock reconfiguring device. Furthermore, the clock reconfiguring device a has late-programmable and low power memory driven by the intermediate clock signal for generating the secondary reconfigured clock signals. These are wave-shape patterns read-out from a plurality of separately and sequentially drivable memory locations.
