    摘要： Asymmetric switching is defined for magnetic bit cell elements. A magnetic bit cell for memory and other devices includes a transistor coupled to an MTJ structure. A bit line is coupled at one terminal of the bit cell to the MTJ structure. At another terminal of the bit cell, a source line is coupled to the source/drain terminal of the transistor. The bit line is driven by a bit line driver that provides a first voltage. The source line is driven by a source line driver that provides a second voltage. The second voltage is larger than the first voltage. The switching characteristics of the bit cell and MTJ structure are improved and made more reliable by one or a combination of applying the higher second voltage to the source line and/or reducing the overall parasitic resistance in the magnetic bit cell element.

    摘要： A duty cycle corrector comprising a first circuit and a second circuit. The first circuit is configured to receive a clock signal and an inverted clock signal and to obtain a delay signal that indicates a time difference between transitions of the clock signal and the inverted clock signal. The second circuit is configured to receive the clock signal and the inverted clock signal and the delay signal and to delay the clock signal based on the delay signal to provide an output clock signal having substantially a 50% duty cycle.

    摘要： An oscillator circuit includes a capacitor device, a current source for supplying a current to the capacitor device, a reference voltage, and a control circuit. The reference voltage is a first input to a comparator. An output of the capacitor device and an output of the current source are a second input to the comparator. The control circuit resets the oscillator circuit when the first and second inputs to the comparator are equal.
