Semidigital PLL Design for Low-Cost Low-Power Clock Generation
Journal of Electrical and Computer Engineering, 2011 This paper describes recent semidigital architectures of the phase-locked loop (PLL) systems for low-cost low-power clock generation. With the absence of the time-to-digital converter (TDC), the semi-digital PLL (SDPLL) enables low-power linear phase ...

Integrated High-Resolution Multi-Channel Time-to-Digital Converters (TDCs) for PET Imaging
, 2011 PET with time-of-flight (TOF) capability has been shown to provide a better reconstructed image compared to conventional positron tomography. The increase in SNR mainly depends on the size of the patient being imaged Conti (2009), the intrinsic resolution of the detector and the resolution of the TOF.

Scientifica, Volume 2026, Issue 1, 2026.Epilepsy is a neurological disorder characterized by repeated, unprovoked seizures arising from abnormal electrical activity in the brain. The management of epilepsy presents several significant challenges. One of these challenges involves drug resistance, where seizures persist despite treatment with multiple antiepileptic drugs, requiring a tailored ...
