Abstract
This paper presents measurement of a variable gain amplifier gain parameters using Frequency Domain Analysis technique to provide a precise amplitude measurement of a 35mVpp AC signal. It also introduces a noise-free small signal measurement. This is a proposed methodology to address the measurement error induced by a high frequent noise riding on the signal to be measured. By using an appropriate analytical tool, the key process input variables were easily determined; critical points connrted to quality points were identified; planned design was properly executed and improvement was implemented. All of the objectives were met, a precise gain measurement to a more precise with accuracy measurement and immune to noise effect into a noise-free measurement approach. This methodology is a beat measurement approach that enhances quality of testing. These are the benefits that were gained lo implementing the introduced methodology this paper.
