ABSTRACT

Radiation detection is a fundamental technique in various applications like radioactivity control, high-energy physics, space science, and medical applications. This chapter presents a synthesizable radiation readout system for radiation detector application-specific integrated circuits (ASICs). The use of (ASIC) readout systems is gaining importance as the implementation of readout electronics and semiconductor detectors onto the same chip offers enhanced detection sensitivity thanks to improved noise performance. A low-noise charge-sensitive preamplifier (CSA) is widely used at the front end due to its low-noise and gain insensitivity to the detector capacitance variations. The chapter proposes an advanced and detailed analysis concerning inverter-based shapers for front-end systems is carried out, and novel shaper designs. The proposed inverter-based self-biased shaper achieves low power consumption and significantly low silicon area. In addition, the modified SAR ADC that completes the full readout analog processor occupies approximately half the area of typical SAR ADCs.
