    摘要： Techniques are provided to reduce glitches at an output signal node when a device is switched to and from a low power operation mode. In one example, a method of operating a device includes providing power to operate a signal source of the device during a normal operation mode of the device. The method also includes passing an output signal from the signal source through a signal path to an output node during the normal operation mode. The method also includes receiving an operation mode signal to switch the device from the normal operation mode to a low power operation mode. The method also includes disabling the signal path to prevent glitches from appearing at the output node during the switch from the normal operation mode to the low power operation mode. The method also includes continuing providing power to the signal source until after the signal path is disabled.

    摘要： A phase locked loop (PLL) circuit is provided with selectable feedback paths. In one example, a method of operating a device includes passing a clock signal provided by a PLL circuit of the device through an internal feedback path of the PLL circuit to provide a first input signal to the PLL circuit while at least one external circuit of an external feedback path of the device is disabled during a low power operation mode of the device. The method also includes detecting a lock between the first input signal and a reference signal during the low power operation mode. The lock indicates that the clock signal is operating at a frequency used during a normal operation mode of the device. The method also includes passing the clock signal through the external feedback path to provide a second input signal to the PLL circuit. The method also includes switching from detecting a lock between the first input signal and the reference signal to detecting a lock between the second input signal and the reference signal if the external circuit is enabled for the normal operation mode.

    摘要： A cross-fill metal fill pattern technique is provided such that portions of a metal fill pattern are patterned to accomplish a secondary function. For instance, in the exemplary embodiments, ever other trace or line of interdigitated fingers is routed to a ground, while the interceding traces or lines of interdigitated fingers are routed to a power supply. In this way, a capacitor function is formed across the power supply, providing additional decoupling for the power supply. Moreover, a suitably tight cross-fill metal fill pattern (i.e., higher density of metal) provides an electrical shielding function for electromagnetic radiation passing therethrough.

    摘要： In an exemplary decision-feedback equalizer (DFE) of a serializer/deserializer (SerDes) receiver, a single current mirror array is shared by multiple current digital-to-analog converter (IDAC) functions. The DFE has an initial amplifier stage that applies an initial coefficient COEFF0 to an input data signal and a number of (e.g., five) additional amplifier stages that apply additional coefficients (e.g., COEFF1-COEFF5) to different delayed versions of the recovered output data stream. The outputs of the initial and multiple additional amplifier stages are summed to generate an equalized data signal that is applied to a clock-and-data recovery (CDR) circuit. Due to certain characteristics of the equalizer function, the multiple additional amplifier stages can be implemented using a single shared current mirror array, which save significant amounts of chip area compared to conventional implementations in which each additional amplifier stage has its own dedicated current mirror array.

    摘要： A chiller system includes a compressor operable at a compressor speed between a first speed and a second speed to deliver a flow of compressed fluid to a manifold at a compressor pressure and a condenser in fluid communication with the manifold to receive the compressed fluid. A condenser fan is operable at a fan speed between a minimum fan speed and a maximum fan speed to direct a cooling flow to the condenser to cool the compressed fluid and an evaporator is positioned to receive the flow of compressed fluid and operable to cool a second fluid. A controller is operable at least partially in response to a measured temperature of the second fluid and a measured temperature of the cooling flow to determine a desired pressure and to vary the compressor speed and the fan speed such that the compressor pressure equals the desired pressure.
