Publication number: 20030006781Abstract: In order to detect performance parameter variations at different locations, local parameter detectors are located at the various local locations. One of the local locations is selected as the reference location while the other local locations are selected as destination locations. The reference location is utilized to determine a reference parameter value, while each destination location compares its local parameter value to the reference parameter value. The parameter values are current encoded and the reference parameter value is sent to the other locations for the comparisons. The comparison at the destination locations each generates a corrective signal to compensate for the difference in the parameter value between the locations. Parameter compensation is provided to reduce performance skew among the distributed locations.Type: ApplicationFiled: June 29, 2001Publication date: January 9, 2003Inventors: Thomas To (Hing-Yan To), Jen-Tai Hsu, Andrew M. Volk

Patent number: 6051999Abstract: A circuit for controlling the bias current in a differential amplifier is disclosed. A differential amplifier comprising complementary differential input transistor pairs includes variable bias current sources to provide bias currents to the differential input pairs. The variable bias current sources are coupled to an input current control unit that includes one or more programmable switches to vary the amount of bias current supplied to the differential input pairs. The slew rate, differential gain, and common mode input range of the differential amplifier may be varied by adjusting the bias currents to the differential input pairs. A cascode circuit is coupled between the differential input pairs and their respective load circuits to extend the common mode input range to the supply voltage rail values.Type: GrantFiled: January 14, 1998Date of Patent: April 18, 2000Assignee: Intel CorporationInventors: Hing Yan To, Jahanshir J.
