For several decades, the output from semiconductor manufacturers has been high volume products with process optimisation being continued throughout the lifetime of the product to ensure a satisfactory yield. However, product lifetimes are continually shrinking to keep pace with market demands. Furthermore there is an increase in dasiafoundrypsila business where product volumes are low; consequently...
The paper presents the design and implementation of input/output interface circuits, fully compatible with low-voltage differential signal (LVDS) standard. Due to the low voltage differential transmission technique, the low power consumption and high transmission speed are achieved at the same time. The transmitter is implemented by a closed-loop control circuit and an internal bandgap voltage reference,...
A high intercept points, cost-effective, and power-efficient switching FET double balanced mixer (DBM) is reported. The Switching FET DBM demonstrated in this work offers input intercept points (IIP3) and conversion loss typically 44 dBm and 8.5 dB respectively with 15 dBm LO power for the frequency band (RF: 900-2150 MHz, LO: 850-1950 MHz, IF: 50-200 MHz). The measured interport isolation is typically...
In order to compare current and logic testing of a static memory cell in the presence of bridging defects, an electrical model for the defective cell is used. The SPICE parameters for the cell have been extracted from the layout and process information. All the extracted bridges are shown to be quiescent current testable. However, for a large percentage of the defects, the logic (voltage) testability...
