Automated Evaluation and Test of Readout Interface for Mems Microphone Prototype Chips

1. Introduction Testing is an important part of design and production of integrated circuits. Such testing of proper function of the circuits consumes a lot of time and resources. It is necessary to set and evaluate lots of parameters in analog testing. It is very inefficient in manual implementation. This testing can be speeded up by using automatic measurements. Professional testing equipment are very expensive. For example, to measure the harmonic distortion is used spectrum analyzer, which is not standard equipment of most labs. Therefore it is necessary to look for other approaches of cheaper testing by using more affordable of measuring instruments. For this purpose, we designed a computer software, which can perform automated measurements by using the function generator and oscilloscope.
