Concept Development and Evaluation
- Review and/or creation of existing specifications, project plans and business plans for IC development
- Review of technical concepts, implementation, and assumptions for new designs or improvements to designs in production
Development of Complex Custom Mixed-Signal ICs
- Combinations of high accuracy and high drive capability in one design
- Multiple power domains on a chip, with voltages from 1 V to 100 V (depending on process technology) with level-shifting and enable/disable control
- System calibration and trimming based on EEPROM cells, flash memory blocks, or fuses
- Systems designed to operate from multiple energy sources (e.g., battery, USB, AC adapter, external supply IC)
- Custom power control systems, including power-up and power-down procedures, hibernation and sleep modes
- Fab expertise with XFAB, TSMC, Silterra, IMEC and GolbalFoundries at different process nodes (high-voltage 0.35 um, 0.13 um, 90 nm, 65 nm, 55nm)
