20100102638 | SYSTEMS AND METHODS FOR DISCHARGING BUS VOLTAGE USING SEMICONDUCTOR DEVICES - Systems and methods are provided for discharging a high-voltage bus using semiconductor devices. A discharge system for a first voltage rail and a second voltage rail comprises a first semiconductor device coupled to a first voltage rail and a second semiconductor device coupled between the first semiconductor device and a second voltage rail. A control circuit is coupled to the first semiconductor device and the second semiconductor device. In response to a discharge condition, the control circuit is configured to activate the first semiconductor device and gradually activate the second semiconductor device, such that the energy potential between the first voltage rail and the second voltage rail is gradually dissipated through the semiconductor devices. | 04-29-2010 |
20100194205 | Isolation circuitry and method for hiding a power consumption characteristic of an associated processing circuit - An isolation circuitry and method are provided for coupling between a power supply and processing circuitry in order to provide power to the processing circuitry whilst hiding a power consumption characteristic of that processing circuitry. The isolation circuitry comprises a plurality of sub-circuits, with each sub-circuit comprising a capacitor, a first switch configured to provide a first connection between the capacitor and the power supply, a second switch configured to provide a second connection between the capacitor and the processing circuitry, and a third switch configured to provide a third connection across the capacitor to partially discharge the capacitor. Control circuitry controls the plurality of sub-circuits, such that within each sub-circuit the first switch, second switch and third switch are placed in an active state in a repeating sequence. Each of the plurality of sub-circuits further comprises a comparator configured to place the third switch in an open state when a predetermined non-zero voltage difference across the capacitor is reached during the active state of the third switch. By such an approach, it is ensured that the voltage across the comparator at the end of the discharge operation is always the same irrespective of the voltage present at the start of the discharge operation. As a result, the power consumption characteristic of the processing circuitry is entirely hidden by the isolation circuitry. Further, the isolation circuitry of the present invention provides a particular power efficient mechanism for hiding the power consumption characteristic of the processing circuitry. | 08-05-2010 |
