摘要： A structure and method for damping LC (inductance-capacitance) ringing in integrated circuit (IC) power distribution systems. The structure comprises a resistance electrically connected in parallel with a plurality of electrical switches. The resistance and electrical switches are electrically connected in series with the package and on-chip power distribution circuit. When on-chip switching activity creates a sudden and appreciable change in IC power demand the electrical switches are opened to temporarily increase the resistance in series with the power supply. This serves to dampen the power-distribution LC ringing. Later, the electrical switches are closed to shunt the series resistance and reduce the level of steady-state voltage drop in the power structure.

摘要： A re-centering system (116) for re-centering the control parameter of a phase lock loop (PLL) (112). The re-centering system includes sources (140) for obtaining/storing operating parameters, such as environmental data (184), setup data (188), and other knowns data (192). At least one state machine (132) utilizes the operating parameters to adjust the topology of the PLL so as to achieve a desirable topology for each target output frequency (18) that substantially centers the performance envelope(s) (120, 124, 128) to a desired pre-selected value of the control parameter. The re-centering system also includes a comparator (136) for comparing measured values of the control parameter to a pre-selected value. The state machine utilizes the output of the comparator to substantially center the corresponding performance envelope at the pre-selected value.

摘要： Disclosed are current sink and source circuits, a charge pump that incorporates them, and a phase locked loop that incorporates the charge pump. The current sink and source circuits each have a current mirror that biases a transistor connected to an output node. These circuits each further have a two-stage feedback amplifier to sense the current mirror drain voltage and to control the transistor gate voltage in order to stabilize the current mirror drain voltage independent of output voltage at the output node. The amplifier also increases output resistance at the output node. This configuration allows for a wide operation voltage range and ensures good circuit performance under a very low power supply. A charge pump that incorporates these circuits generates highly matched charging and discharging currents. A PLL that incorporates this charge pump exhibits minimal bandwidth shifts and minimal locking speed and jitter performance degradation.
