    摘要: Techniques are provided for controlling an on-chip termination resistance in an input or output (IO) buffer using a calibration circuit. The calibration circuit monitors the voltage between an external resistor and a group of on-chip transistors. When voltage between the external resistor and the group of transistors is within a selected range, the calibration circuit causes the effective resistance of the transistors to match the resistance of the external resistor as closely as possible. The calibration circuit enables another set of transistors in the IO buffer so that the effective on resistance of the transistors in the IO buffer closely match the resistance of the external resistor.

    摘要: Circuits and methods are described for producing a DLL clock signal with adjustable phase shift using a processed control signal. In one embodiment of the invention, a DLL circuit is provided that includes a main and smaller variable delay circuits, a phase detector and an up down counter that provides a main control signal to adjust the delay by the main variable delay circuit. When the DLL circuit is locked, an arithmetic logic unit (ALU) produces a processed control signal based on the main control signal, an ALU control signal and an offset control signal, and the processed control signal is provided to the smaller variable delay circuit. By adjusting the ALU control and offset control signals, the phase shift introduced on the DLL control signal by the smaller variable delay circuit can be adjusted. In another embodiment of the invention, a second up down counter is used in place of an ALU for providing a dynamically adjustable phase shift in accordance with the principles of the present invention.

    摘要: Circuits, methods, and apparatus for deskewing rising and falling edges of a clock signal. One embodiment of the present invention utilizes a delay element in a data path to adjust a data signal such that a clock signal is centered relative to the data. A further embodiment of the present invention recovers a double-data rate signal using two flip-flops, one clocked by clock rising edges, the other clocked by clock falling edges. An additional delay element is inserted in front of one or both flip-flop clock inputs. If two additional delay elements are used, they are independently adjustable such that each edge can be independently adjusted for improved data recovery.

    摘要: A method and apparatus for updating the control signal received by a delay chain in a DDR application. A register is used to regulate the control signal to the delay chain. The register only updates the signal at the delay chain when a signal is not passing through the delay chain. Additionally, the present invention is directed to a delay circuit that uses a plurality of PMOS and NMOS transistors connected in parallel to each other and to an inverter that provides the desired delay. The delay provided is achieved by sequentially turning off/on a series of the NMOS/PMOS transistor pairs.

    摘要: A soldering iron which is developed specifically to address a wide variety of miniaturized integrated circuit soldered pin configurations has a handle with a heating block which mounts one of a set of wide, chisel-shaped blades that are engaged in a deep channel in the heating block and which taper gradually to a knife edge which is the operative edge of the soldering head. The wide, thin, extensively tapered and knife-edged blade usually addresses a row of integrated circuit pins or surface mounted leads to act brush-like to solder them substantially at the same time, or to heat them substantially simultaneously when desoldering the row to remove the component.
