20100052840 | LOW VARIATION RESISTOR - This document discloses low variation resistor devices, methods, systems, and methods of manufacturing the same. In some implementations, a low-variation resistor can be implemented with a metal-oxide-semiconductor field-effect-transistor (“MOSFET”) operating in the triode (e.g., ohmic) region. The MOSFET can have a source that is connected to a reference voltage (e.g., ground) and a gate connected to a gate voltage source. The gate voltage source can generate a gate voltage that varies in proportion to changes in the temperature of an operating environment. The gate voltage variation can, for example, be controlled so that it offsets the changes in MOSFET resistance that are caused by changes in temperature. In some implementations, the gate voltage variation offsets the resistance variance by offsetting changes in transistor mobility that are caused by changes in temperature. | 03-04-2010 |
20100156588 | RESISTOR STRUCTURE OF PHASE CHANGE MATERIAL AND TRIMMING METHOD THEREOF - An embodiment of a resistor formed by at least one first portion and one second portion, electrically connected to one another and with different crystalline phases.

20110273263 | Near Zero TCR Resistor Configurations - A microchip resistor device is disclosed in which first and second resistive elements are formed on a substrate. The first resistive element has a first resistance value and a positive temperature coefficient of resistance (TCR) over a selected temperature range. The second resistive element has a second resistance value and a negative TCR over the selected temperature range. The first and second resistive elements do not overlap each other. The first and second resistive elements are operatively connected with one or more conductors to provide a current path between the two elements. The product of the first resistance value and the positive temperature coefficient of resistance is substantially equal in magnitude to the product of the second resistance value and the negative temperature coefficient of resistance. | 11-10-2011 |
