Ultra Compact and Low-power TDC and TAC Architectures for Highly-Parallel Implementation in Time-Resolved Image Sensors


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… (More)
