ABSTRACT

The current trend in high-energy physics, biomedical applications, radioactivity control, space science, and other disciplines that require radiation detectors is toward smaller, higher-density systems to provide better position resolution. Miniaturization, low power dissipation, and low-noise performance are stringent requests in modern instrumentation where portability and constant increase of channel numbers are the main streamlines. In most cases, complementary metal–oxide semiconductor (CMOS) technologies have fully proven their adequacy for implementing data acquisition architectures based on functional blocks such as charge preamplifiers, continuous time or switch–capacitor filters, sample-and-hold amplifiers, analog-to-digital converters, etc., in analog signal processing for particle physics, nuclear physics, and x- or beta-ray detection [1–3].
