Greyrock Technology engages with customers at various business levels, from work-for-hire through intellectual property development and licensing. We use the latest Cadence design tool flow end to end, but also have professional experience with most major analog and digital design tools.

We've worked with each of the major semiconductor foundries, recently taking designs to production in 180nm and 130nm CMOS processes. Our experience includes designing successfully with and without precision analog and/or power process modules.

Primary areas of design and consulting include:

• Analog circuit design
• Serial transceiver design
• Mixed-signal design and test architectures
• Low-noise and low-power architectures
• Design for ESD protection
• Circuit and system characterization
• DDR memory interfacing
• Circuit board layout for high-performance analog
