Voltage and Frequency Dependence on Resistors

Posted by Tomáš Zedníček

Voltage Dependence If we apply a voltage on a resistor it’s resistance will drop slightly in certain types. Therefore the resistance change is negative. The change per volt of applied voltage is called voltage coefficient, VC, and is expressed in %/V or better, μV/V. The coefficient is determined not only by the resistive material but also by the dimensions, i.e., the electrical field strength, and the time of applied voltage. Thus, MIL-STD-202, Method 309 prescribes measurements when the voltage is applied intermittently for less than 0.5 seconds.

Learn how to reduce second harmonic distortion by following some guidelines for placing decoupling capacitors in your PCB layout in article from Steve Araras published by All About Circuits. In this article, we’ll see that, without proper decoupling, we cannot extract the maximum linearity performance from a high-speed op-amp. In addition, we’ll discuss that simply rearranging a decoupling capacitor can affect the distortion performance of a high-speed amplification stage.
