Description

The Programmable Read-out with Improved Noise-performance Charge Sensitive Amplifier (PRINCSA) is a prototype ASIC dedicated for radiation imaging using silicon microstrip sensors.

The IC was designed to meet the tight requirements of the tracking detectors for High-Energy Experiments: low noise, charge processing speed (expected, near megahertz interaction rates), parameters uniformity in many channels, linearity up to 12 pF signal, and good resolution of time and amplitude measurements [1].

The main goal of this project was optimization of the overall system noise expressed as Equivalent Noise Charge, ENC lower than 1000 e- rms. The power supply interference is one of the factors that may compromise the charge measurement capabilities.

Why EUROPRACTICE?

Our department has used EUROPRACTICE service for many years. It is affordable and easily available for the prototyping purposes for teaching and research, especially for Ph.D. students. The mini@sic program is an excellent and cost-effective choice to test several new ideas and circuitries. We also appreciate the well-qualified technical support team, which is very important for the successful tape-out process.
