摘要： In one embodiment, an integrated circuit (IC) includes a power distribution network having a first set of power distribution lines connected to a source voltage and a second set of power distribution lines connected to a ground voltage, and a first capacitor. A first variable resistive element is electrically coupled in series with the first capacitor between the first and second sets of power lines of the power distribution network. A control circuit is coupled to the variable resistive element and is configured and arranged to adjust a level of resistance of the first variable resistive element in response to an input signal. The adjustment of the level of resistance adjusts an equivalent series resistance of the power distribution network.

摘要： A low phase noise high speed stabilized time base uses a crystal resonator that operates directly at a desired high frequency of one hundred to several hundred MHz. An inverted mesa AT-cut quartz crystal meets this criteria. To promote frequency stability the crystal and its oscillator circuit are thermally clamped to a convenient temperature that need be only loosely regulated, say, at about room temperature. In an exemplary ATE setting that already provides a water flow heat removal system whose supply side is 26° C.,±0.5° C., a 400 MHz inverted mesa AT-cut crystal is simply given its own loop within that water supply. Other temperature stabilization techniques for loose regulation, such as Peltier cells, may be used. The result is a high frequency time base having adequate frequency accuracy and stability, but with the extremely low timing jitter of just the crystal resonator, since there is no contributory timing jitter from a frequency multiplying PLL.
