Arrayable TDC with Voltage-Controlled Ring Oscillator for dToF Image Sensors [PDF]

open access: yesSensors
As the resolution and conversion speed of time-to-digital conversion (TDC) chips continue to improve, the bit error rate also increases, leading to a decrease in the linearity of TDC and seriously affecting measurement accuracy.

Integrated High-Resolution Multi-Channel Time-to-Digital Converters (TDCs) for PET Imaging

open access: hybrid, 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.

TDC–CiM: Time–to–Digital Converter–Based Resonant Compute–in–Memory for INT8 CNNs with Layer–Optimized SRAM Mapping

open access: greenIEEE Journal on Emerging and Selected Topics in Circuits and Systems
In recent years, Compute-in-memory (CiM) architectures have emerged as a promising solution for deep neural network (NN) accelerators. Multiply-accumulate (MAC) is considered a de facto unit operation in NNs. By leveraging the inherent parallel processing capabilities of CiM, NNs that require numerous MAC operations can be executed more efficiently ...
