摘要： A method and circuit for pre-emphasis equalization of a high speed data communication system can be provided through the use of programmable pulse shaping. A data communication system configured with the pre-emphasis equalization circuit operates by receiving an input data stream and outputting a data stream for transmission through an interconnect or other transmission channel. The data can be passed through an output buffer configured with programmable pre-emphasis equalization, having input inverters at an input stage and output inverters at an output stage. During operation, once an input signal to the input stage transitions, for example from a low to a high state, an input signal to the output stage is configured to a full amplitude to drive the transmission channel. Once the output stage transitions to a full amplitude, the input of the output stage is configured closer to a mid-scale amplitude. The amount of amplitude change from full scale back to mid-scale determines the amount of equalization to be provided by the output buffer to the transmission channel.

摘要： A switching regulator includes a power stage for coupling to a load through an inductor. The power stage switches so that the power stage sources positive current to the load through a first transistor of the power stage during some periods and sinks negative current from the load through a second transistor of the power stage during other periods. The switching regulator further includes a protection circuit operable to force the second transistor into an off-state state responsive to the negative current flowing through the inductor exceeding a predetermined negative threshold.

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： Disclosed is a power regulator for providing precisely regulated power to a microelectronic device such as a microprocessor. Improved power regulation is accomplished by optimizing the power efficiency of the power regulator. In particular, in a multiphase system, the number of active phases is increased or decreased to achieve optimum power efficiency. The multiphase voltage regulator adapts the operating mode to maximize efficiency as the load current demand of the load device changes by adjusting the number of active phases to maximize efficiency. The total value of current provided by the regulator and the total number of active phases is determined, the total number of active phases is compared with the number of active phases required to provide the total value of current at maximum efficiency; and the number of active phases is adjusted to provide the total value of current at maximum efficiency.A current sense circuit senses the current at each phase, a summing circuit coupled to the output of the current sense circuit provides the total current value of all the measured phases, a circuit coupled to the output of the summing circuit provides the time averaged total current value to a threshold detecting circuit that determines the number of phases at which the voltage regulator should be operating for maximum efficiency, and a circuit for comparing the number of phases that are operating to the number of phases at which the voltage regulator should be operating adjusts the number of active phases to the number of phases at which the voltage regulator should be operating for maximum efficiency.

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 predetermined 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. The AVP load line is pre-positioned for more precise current control. Also disclosed is an adaptive filter with adjustable frequency characteristics in response to an ATR event. Also disclosed is a pulse limiting circuit. Also disclosed is a tri-state implementation. Response to transient events is further improved with an external ATR circuit coupled to the load.
