Laboratory of Microelectronics – INFN Napoli Section
The Laboratory of Microelectronics of the INFN Napoli Section is dedicated to design and test of analog/digital electronics applied to detector readout and optical transmission, as well as in organic biosensors. The Laboratory is equipped with state-of-art instrumentation for IV and CV characterization of sensors and components, and to perform noise analysis starting from 1 Hz. Moreover, it has advanced instrumentation to perform analysis in the frequency domain and to provide time-correlated acquisition of analog, digital, and RF signals and to make measurements in both the time and frequency domains simultaneously.
Here’s a list of the technical specifications of measurements that can be performed in the lab:
• low level DC current characterization
• high-sensitivity (~ fA/Hz1/2) noise characterization in the low frequency range (<100 kHz)
• time and frequency domain analysis
• impedance measurements
• automatic and programmable DC, Low frequency Noise and Impedance measurement workflow
In the following, we list the main techniques and instruments available in the lab.
Parametric Analysis
IV and CV characterization of sensors and components is handled by the B1500A Semiconductor Parameter Analyzer equipped with four high-resolution SMU channels. The analyzer combines DC and AC tests and it supports various measurement techniques, including IV, CV, pulse/dynamic IV, and more. It also can capture ultra-fast transient phenomena, feature not supported by other conventional test instruments.
Noise Analysis – E5052B Signal Source Analyzer
For noise analysis starting from 1 Hz, we have in our lab the E5052B Signal Source Analyzer. This analyzer is capable of very fast, yet accurate noise measurements. This is extremely useful when sensor working conditions can change during the test.
Probe Station
Our lab is equipped with a measurement setup based on a probe Station to house the device under test (DUT), sample illumination lamp (LAMP), optical camera (Camera) for display of the sample on a PC.
Mixed Domain Oscilloscope: Tektronix MDO4104-6
The MDO4104-6 Mixed Domain Oscilloscope has a 1 GHz Bandwidth and a 5 Gs/s sample rate, and it provides time-correlated acquisition of analog, digital, and RF signals instrument. It can be used to verify, debug, and characterize electronic designs by providing views and measurements in both the time and frequency domains simultaneously.
