tac (time to amplitude convertor) is one of the most important time measurement instrumentswhich has great significance in many fields of science, especially radiation physics. a tac unit has beendesigned based on the start-stop analog method and nim (nuclear instrument modules) standards. afterdesigning the circuit, it was simulated by pspice software and constructed by discrete and integrated...

A new integrated front-end electronics, based on a high resolution Time-to-Amplitude Converter ASIC chip (TAC), has been developed for time measurements in a time of flight experiment (RPC-detectors) of several thousand channels [1]. A sixteen channel board, named TACQUILA, with a time resolution of about 10ps RMS, has been built. It consists of a TAC stage and a 12 bit ADC for each channel fol...

A high resolution Time Correlated Single Photon Counting (TCSPC) image sensor based on sample and hold Time to Amplitude Converter (TAC)pixels and a global ramp voltage is presented. The 256× 256 array achieves an 8 μm Pixel Pitch (PP), 19.63% Fill Factor (FF), output voltage range (0.7V) and time jitter of 368 ps at 10 fps employing an off-chip 14-bit differential Analogue to Digital Converter...

In nuclear spectroscopy, by definition, a distorted signal from saturated preamplifier cannot contain the correct energy information, being this one directly related to amplitude. work, we propose an innovative technique exploit charge-conservation principle extract high-resolution information deeply charge-sensitive (CSP) connected semiconductor detectors. The previously described “fast-reset”...

Abstrac t We report on the design and characterization of three different architectures, namely two Time-toDigital Converters (TDCs) and a Time-to-Amplitude Converter (TAC) with embedded analog-to-digital conversion, implemented in a 130-nm CMOS imaging technology. The proposed circuit solutions are conceived for implementation at pixel-level, in image sensors exploiting Single-Photon Avalanche...

This paper presents a modified nine switch inverter with two inputs and two Z-source networks. This inverter has two DC inputs and two AC outputs. Input DC voltages can be boosted to the required level. Amplitude, frequency and phase of AC output voltages can be controlled, independently. The proposed converter can be used in applications with two unregulated DC sources, which require feeding ...
