Positron emission tomography architectures have been traditionally dependent on zero crossing discriminators, external voltage references, or fixed voltage references with restricted voltage steps. This paper presents a digital-to-analog converter (DAC) utilized to set the threshold voltages of Time-of-Flight Positron Emission Tomography (TOF-PET) comparators. The DAC circuit uses a charge redistribution...
A 1-V 5.8 GHz CMOS front-end applying in dedicated biomedical systems has been successfully implemented by TSMC 0.18 µm CMOS process. This system has built in near-infrared laser-driven (NIRLD) might be a promising wireless electrical power source and phase in wake up receiver technology using direct active RF detection for biomedical nanodevices power saving. This proposed prototype includes an input...
