摘要： Disclosed is a multi-phase power regulator that accurately senses current at a load in a lossless manner and adjusts the power supplied to the load based on the sensed current. Also disclosed is a method of calibrating a multiphase voltage regulator by applying a known calibration current at the load and determining actual current values by the difference in measured values between when the known calibration current is applied and when it is not applied. The accurate current is determined at a known temperature and accurate temperature compensation is provided by a non-linear digital technique. Each phase of the multi-phase power regulator is individually calibrated so that balanced channels provide accurate power to the load. Also disclosed is a calibration method with minimal noise generation.

摘要： A dual loop (PLL/DLL) data synchronization system and method for plesiochronous systems is provided. A dual loop data serializer includes a phase lock loop (PLL) and a delayed lock loop (DLL) configured with a phase shifter in the feedback path of the PLL. The dual loop serializer locks to the input of the DLL instead of the local reference. Thus, the DLL adjusts the frequency from the PLL so that it matches the desired data rate. Each loop may be optimized for jitter tolerance with the net effect generating a synthesized clean clock (due to narrow bandwidth filtering) and VCO noise suppression (due to wide bandwidth filtering). A dual loop retimer includes a dual loop serializer (PLL/DLL) and a clock recovery DLL. The retimer resets the jitter budget to meet transmission requirements for an infinite number of repeater stages.

摘要： A device for providing power to suppress transient load demands and a system including the device are disclosed. The device includes a sense circuit to detect when a transient event occurs and one or more transistors configured to supply or sink current to the load. The system may include a second power regulator configured to respond to fast transient power demands. In this case, a first power regulator supplies power to the load and responds to slow transient events, while the second regulator responds only to fast transient events.

摘要： Disclosed is a multi-phase pulse width modulated voltage regulator and method in which transient voltage excursions or deviations that exceed the load line voltage by more than a pre-determined amount are detected by an ATR circuit and a correction signal is applied. The correction signal is in the form of asynchronous pulses and the number of such pulses is a function of the magnitude of the voltage excursion as determined by the number of thresholds that are exceeded. Also disclosed is an adaptive voltage positioning (AVP) circuit and method for early detection of a transient event by sensing voltage changes at the load and adjusting the target voltage with pre-determined current values prior to the time that ATR event changes in the current at the load are detected.
