An optimal way to determine an op amp's input capacitance. Steps involved in making the input-capacitance measurement. 1. With a series resistor at the op-amp input, the input capacitance of the op ...
This paper defines a method to measure the chip die pad capacitance using time delay reflectometry (TDR). This method is useful for measuring the low-value capacitance that is present at the end of a ...
Irregularities on a surface determine how rough it is. Surface roughness can be evaluated by visual appearances and tactile sensation and can be measured using a numerical scale. A surface condition ...
