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： 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 transconductor is provided having a transconductance G.sub.m. This transconductance is then attenuated with a steering circuit (41) to attenuate the overall transconductance of the transconductor and vary the bandwidth. A fixed voltage is then input to the transconductor with the output thereof offset with a programmable current DAC (48). This output is then provided to an error amplifier (46) for developing an error voltage. This error voltage is then input back to the input of the transconductor to adjust the transconductance thereof to minimize this error. The steering circuit (41) is controlled by a voltage DAC (58) to program the attenuation provided thereby. Both the voltage DAC (58) and the current DAC (48) are controlled by a bandwidth control signal to program the bandwidth of the overall transconductor. This is facilitated while compensating for the process and temperature variations of the transconductance of the transconductor. This is also facilitated with a master/slave relationship.
