The mixed-signal circuits with both analog and digital blocks on a single chip have wide applications in communication and RF circuits. Integrating these two blocks can cause serious problems especially in applications requiring fast digital circuits and high performance analog blocks. Fast switching in digital blocks generates a noise which can be introduced to analog circuits by the common su...

We present a mixed-signal implementation of a re-configurable polychronous spiking neural network capable of storing and recalling spatio-temporal patterns. The proposed neural network contains one neuron array and one axon array. Spike Timing Dependent Delay Plasticity is used to fine-tune delays and add dynamics to the network. In our mixed-signal implementation, the neurons and axons have be...

IC design is facing significant challenges beyond the 40-nm process technology node because of increased process variation and its impact on circuit behavior and performance. At advanced process nodes, the increasing number of layers and new device structures result in hundreds of new parameters and many new parasitic effects, which require higher levels of accuracy in modeling and parasitic ex...

BACKGROUND In the intraoperative consultation of ovarian tumors, the histological diagnosis of frozen sections (FS) of large tumors is frequently difficult because of the limited number of tumor samples. The application of imprint cytology (IC), in which samples are obtained from wide areas of the tumors, is useful for intraoperative consultation. However, the useful aspects of IC have not been...

Modern System-on-Chip (SoC) designs are increasingly mixed-signal Very Large Scale Integrated (VLSI) designs that require efficient design and testing methodologies to manage the design complexity and the time-to-market constraints. Also, in mixed-signal integrated circuits (ICs), testing analog cores is the most difficult task and it’s one of the major cost factors in the overall IC manufactur...
