| titleOfInvention | Method and apparatus for extracting noise parameter |
| abstract | (57) [Summary] PROBLEM TO BE SOLVED: To extract 1 / f noise in a parameter extraction technique showing its bias base current dependence, the conventional method requires a large amount of measurement data for extraction and takes a long time. It is another object of the present invention to shorten the parameter extraction time. SOLUTION: One of the silicon bipolar transistors is provided. In the method for extracting a noise parameter representing the bias base current dependency of / f noise, an emitter electrode of the bipolar transistor is grounded, a first bias voltage is applied to a collector electrode through a first variable resistor, and a second bias voltage is applied to the base electrode. (2) In a circuit for applying a second bias voltage via a variable resistor and measuring a root-mean-square noise voltage generated at both ends of the first variable resistor, an arbitrary frequency in a frequency region where the frequency characteristic of the noise voltage is 1 / f And extracting the noise parameter based on the dependence of the noise voltage on the base current at step (i). |
