In the power and energy balance, Freescale's innovators reign
Freescale is a leader in power management techniques. We recognize that power and energy are the biggest challenge facing designers and customers across a broad range of markets and applications. We are attacking power management at every level, from process and design technologies to system-level design and development software.
Everything we do is designed around power management that provides customers the greatest application possibilities.
Leading the Way in Cutting-Edge Techniques
We've developed and perfected processes and techniques enabling low-power performance, including
- Active well bias
- Metallization IR drop reduction
- Dynamic voltage frequency scaling
- Dynamic process temp control
- Level shifting
- State retention power gating
- Ultra low leakage transistors/circuit tech
- Dynamic correction of timing in DVFS
We've revolutionized transistors in several areas, including—
- High mobility/injection velocity (STRAIN)
- High drive current for low intrinsic delay
- Retain gate control over channel
- Minimize OFF-state drain-source leakage
- Reduced extrinsic resistance (ErSi, PrSi)
- Low K spacers
- Laser anneals
- Gate Dialectric
- Gate leakage/scaling
- Reduced power consumption
- Metal Gates
