    • A method for trimming impedance matching devices in high-speed circuits includes determining an electrical parameter associated with a first tantalum nitride (TaN) resistor used as an impedance matching device in the circuit under test, and comparing the determined electrical parameter associated with the first TaN resistor to a desired design value of the electrical parameter. The resistance value of the first TaN resistor is altered by application of a trimming voltage thereto, wherein the trimming voltage is based on a voltage-resistance characteristic curve of the first TaN resistor. It is then determined whether the altered resistance value of the first TaN resistor causes the electrical parameter to equal the desired design value thereof, and the altering of the resistance value of the first TaN resistor by application of a trimming voltage is repeated until the electrical parameter equals the desired design value thereof.
    • 一种用于微调高速电路中的阻抗匹配装置的方法包括:确定与在被测电路中用作阻抗匹配装置的第一氮化钽(TaN)电阻相关联的电参数,并将确定的与第一TaN相关的电参数进行比较 电阻到所需的电参数设计值。 通过施加微调电压来改变第一TaN电阻器的电阻值,其中微调电压基于第一TaN电阻器的耐电压特性曲线。 然后确定第一TaN电阻器的改变的电阻值是否使电参数等于其期望的设计值,并且重复通过施加微调电压来改变第一TaN电阻器的电阻值,直到电参数 等于其期望的设计值。
