Multichannel readout system for registration of electronic system temperature response with high temporal resolution

This paper presents the design and the practical realization of a measurement system dedicated to fast real-time multichannel registration of electronic system thermal response. The response is registered in parallel channels with a frequency up to 1 MHz- Such a high frequency is required for the thermal identification of electronic systems. The designed circuit is used here for the investigation of a thermal test ASIC. The presented solution can be extended for a different number of measurement channels and adapted for other types of sensors.
