摘要： A clamper circuit for receiving an input signal from a victim wire, the clamper circuit being capable of receiving aggressor signals from aggressor wires, the aggressor wires being the signal wires that can potentially induce crosstalk on the victim wire and an output signal being selectively enabled based on the logic states of the input signal and the aggressor signals, the clamper circuit also being capable of accelerating the switching of the victim wire when an opposite transition occurs on the aggressors and victim wire at the same time, so as to thereby reduce worst case delay and improve the signal integrity.

摘要： The present invention relates to a method and circuit arrangement for controlling performance of an integrated circuit in response to a monitored performance indicator, wherein power supply of the integrated circuit is controlled based on said performance indicator. At least one of a noise level of the controlled power supply and a clock frequency generated in said integrated circuit is monitored and a respective control signal is fed back to the controlling function if the checking result is not within a predetermined range. Thereby, an simple and easily extendable automatic adaptation to process variations can be achieved.

摘要： The present invention relates to a control system and method of controlling at least one performance parameter of an integrated circuit. The at least performance parameter is controlled based on a control word. However, the signaled control information is reduced to a binary control signal simply instructing increase or decrease of said at least one performance parameter. This is achieved by modifying the control word in accordance with the binary control signal, e.g., by using the binary control signal to define a binary value shifted into a shift register means (31). Thereby, a fast and simple control functionality can be provided, which does not require any further hardware to adjust the performance parameter.

摘要： An integrated circuit (100) has a circuit portion (102) that can be switched to a standby mode through an enable transistor (104), which is coupled between an internal power supply line (120) and an external power supply line (130). The enable transistor (104) is controlled by control circuitry via a control line (160). The control line (160) is coupled to the gates of a first transistor (152) and a further transistor (154) of a logic gate (150). The substrate of the further transistor (154) is coupled to a backbias generator (170). Consequently, when the enable transistor (104) is switched off, the further transistor (154) is enabled and applies a substantial backbias to the gate of the enable transistor (104), thus dramatically reducing the leakage current from the circuit portion (102) through the enable transistor (104).

摘要： A power supply arrangement is for supplying power to a chip core. A dc-dc converter arrangement is used both for a wake-up state of the core in preparation for an active state, and for a shut down charge recycling state in which the core supplies charge to the dc-dc converter. Thus, the dc-dc converter arrangement functions both to control powering on of the core in an efficient manner and the powering down of the core to implement charge recycling. In an active state, the core is supplied with power from the high power supply line.

摘要： The present invention relates to a circuit arrangement and method of controlling power consumption of the circuit arrangement, wherein a load applied at a circuit component is determined and the drive capacity of the circuit component is adjusted responsive to the determination result. In particular, the circuit component is tailored to have just sufficient drive capacity depending on the potential load which may be determined by examining a configuration information loaded to the circuit arrangement. Tailoring for sufficient drive can be achieved either by varying the size or number of circuit components or by adjusting the threshold voltage of circuit elements, or by doing both. Thereby, power consumption can be reduced when circuit components are driven at loads lower than the worst case load.
