    摘要: A level shifting device comprises an input stage, a cascode stage, a cross-coupled stage, and an output stage. The input stage may receive a data signal or binary logic input in a first data range, a complement of the data signal, and a first voltage. The cascode stage may receive a first voltage and may be connected to the input stage. The cross-coupled stage may be adapted to isolate the first voltage and may be connected to the cascode stage. The output stage may receive a second voltage, provide an output, and be connected to the cross-coupled stage.

    摘要: A timing circuit independently controls placement of the positive and negative edges of a periodic signal. This signal may then be used to control a wide variety of integrated circuit applications. The timing circuit includes separate programmable delay lines and a signal processor. Each delay line delays an input clock signal by a different increment of time. The signal processor then generates a timing signal from the clock signal, where the timing signal has a first edge controlled by the first delayed clock signal and a second edge controlled by the second delayed clock signal. The edges may be controlled so that the timing signal assumes different logical values for different amounts of time, thereby customizing the signal to any application. An example of one application includes using the timing signal control switching in a DC-DC converter.
