| 20080284468 | METHOD AND APPARATUS FOR CONTROLLING A COMMUNICATION SIGNAL BY MONITORING ONE OR MORE VOLTAGE SOURCES - An integrated circuit is capable of controlling a communication signal by using power ramp controlled communication buffer logic to generate an outgoing communication signal based on a detected voltage on a voltage source. The voltage source is necessary to supply power for power ramp controlled communication buffer logic. The voltage on the voltage source may be detected using power ramp sensor logic. The outgoing communication signal is based on a core logic output signal if the detected voltage is greater than or equal to a predetermined voltage level. If, the detected voltage is less than the predetermined voltage level, the outgoing communication signal is predetermined to be one of: a tristate outgoing communication signal, a logic one outgoing communication signal and a logic zero outgoing communication signal. Power ramp controlled communication buffer logic may also generate a core logic input signal based on an incoming communication signal in response to the detected voltage. | 11-20-2008 |
| 20090086865 | Differential Signal Comparator - A differential signal comparator includes an input circuit operative to provide an absolute input current difference value that is associated with the absolute difference of differential input signal levels, and a reference circuit operative to provide an absolute reference current difference value that is associated with the absolute difference of the reference signal levels. Current comparison of the absolute input current difference value with the absolute reference current difference value identify whether an input differential signal is bigger than the reference noise level and should be processed, or an input differential signal is smaller than the reference noise level and should not be processed. | 04-02-2009 |

| 20100149701 | ELECTROSTATIC DISCHARGE CIRCUIT AND METHOD - A method and integrated circuit renders a shunt structure non-conductive during a power up event or noise event for and in addition, during an electrostatic discharge event, keeps the shunt structure conductive for a period of time to discharge electrostatic energy through the shunt structure. In one example, a shunt structure, such as a transistor, is interposed between a power node and a ground node. Circuitry is operative during a power up event or noise event, to render the shunt structure non-conductive for a period of time during the power up event or during the noise event (when power is applied). Second circuit is operative, during an electrostatic discharge event, to keep the shunt structure conductive for a period of time to discharge electrostatic energy through the shunt structure. In one example, a plurality of resistor/capacitors (RC) circuits are utilized wherein the RC circuits have different time constants. In addition, an ESD feedback circuit is employed in conjunction with control logic to suitably control the ESD control logic during an ESD event. Circuitry is also used during a power up event to render the shunt structure non-conductive. | 06-17-2010 |
| 20100161261 | Method and Apparatus for Integrated Circuit Temperature Control - A method includes generating a first, second and third voltage output from a temperature sensing element of an integrated circuit using a respective, corresponding first, second and third, switched current source, for sequentially switching a respective first, second and third excitation current through the temperature sensing element, wherein the third switched current source generates the corresponding third voltage output as a reference voltage between the first voltage and the second voltage; and calculating an error corrected difference between the first voltage and the second voltage using the reference voltage. In the method, the second excitation current is proportional to the first excitation current by a value n, and the third excitation current is proportional to the first excitation current by the square root of n. | 06-24-2010 |
