Abstract: Described is an apparatus having a non-linear control to manage power supply droop at an output of a voltage regulator. The apparatus comprises: a first inductor for coupling to a load; a capacitor, coupled to the first inductor, and for coupling to the load; a first high-side switch couple to the first inductor; a first low-side switch coupled to the first inductor; a bridge controller to control when to turn on and off the first high-side and first low-side switches; and a non-linear control (NLC) unit to monitor output voltage on the load, and to cause the bridge controller to turn on the first high-side switch and turn off the first low-side switch when a voltage droop is detected on the load.

Abstract: An embodiment of the present invention is a technique for thermal sensing. A sensing structure generates a response according to a local temperature at a first location on a die. A sensor core coupled to the sensing structure via routing lines to provide a measurement of the local temperature from the response. The sensor core is located at a second location remote to the first location and is powered by an analog supply voltage source located in a vicinity of the second location.

Abstract: A voltage regulator includes an amplifier having first and second outputs, a feedback path coupled between a first input and the first output of the amplifier, and a feed-forward path between the second output of the amplifier and a switch coupled to a reference potential. In operation, a first control signal from the second output of the amplifier is generated based on a comparison of a reference signal and a feedback signal into the first input of the amplifier. The first control signal controls the switch to maintain a substantially constant supply voltage. A second control signal is generated along the feedback path to control controls the amount of supply voltage.

Abstract: A clock generating circuit is provided that includes a multiplexing device coupled to a clock distribution network to select between a synchronous mode and an asynchronous mode. The device may also include a plurality of distributed ring oscillators to drive the clock distribution network in the asynchronous mode. In the synchronous mode, the multiplexing device may pass a signal from a phase lock loop circuit located external to a core.

Abstract: An apparatus for deskewing clock signals in a synchronous digital system. The apparatus contains a phase detection circuit that receives a plurality of clock signals and generates an output based on a phase relationship between those clock signals. A controller then receives the output of the phase detector and determines which one of the plurality of clock signals requires adjustment based on the output of the phase detector and a bit from a delay shift register. The controller transmits a delay signal to one of a plurality of delay circuits which modifies the delay of the clock signal that the controller determined to require adjustment.

Abstract: The present invention combines in either a logical AND function of N logical input signals, where N is a selected positive integer greater than or equal to 1, and provides programmably, either a direct AND output signal or a NAND output signal. The invention accomplishes this using a minimum number of components in the data path, between the logical input leads and logical output leads. A minimum of components in the data path reduces the propagation delay introduced by the circuit. The invention accomplishes this by providing two AND gates connected to the same set of N logical input signals. The output signal of one AND gate is inverted by an inverter with an enable/disable input lead. The output signal of the other AND gate is inverted twice by two inverters. The second inverter has an enable/disable input lead. Means are provided for exclusively enabling one or the other of the two inverters with an enable/disable input lead.
