Empowering Success
Through Custom ASICs
The Industry Experts In ASIC Design and Manufacturing Services with Specialization in Analog, Mixed-Signal, High-Voltage, and Wireless Communication
Who We Are
Your Mixed-Signal ASIC Partner
Custom Silicon Solutions (CSS) develops and supplies custom microchips with a focus on analog, mixed-signal, high-voltage, and wireless communications. Our Application Specific Integrated Circuits (ASICs) have empowered countless customers to become leaders in their markets with the competitive advantages of a custom design.
As a fabless ASIC company, we partner with leading IC fabs and assembly houses while managing the entire product lifecycle. Our 8,000 sq. ft. test facility in Irvine, CA, provides in-house wafer probe and final packaged production testing.
CSS designs turnkey ASICs from any stage—whether it’s a concept sketched on a napkin or a complete specification. We also create drop-in replacements for obsolete parts and offer flexible engagement models that integrate seamlessly with customer design inputs, large or small.
30 Years, 300 Tape Outs, 100% Success
Mixed-Signal Turnkey ASICs
For nearly three decades, CSS has specialized in the design and manufacture of custom analog, mixed-signal, RF, and high-voltage ASICs. With over 300 tape-outs, CSS has built up a wealth of design, system, and application knowledge that has allowed us to successfully take all fully committed programs to production status.
Our mission is to help customers lead their markets by turning innovative product ideas into low-cost, high-performance ASICs. Each custom design reduces BOM cost, power consumption, and size—while boosting performance, reliability, and intellectual property protection.
Unlike off-the-shelf components, ASICs eliminate wasted power, space, and functionality. They enable performance levels and unique form factors that discrete solutions simply cannot achieve. An ASIC design is always optimized to perfectly fit the needs of the application.
We Specialize
Market Expertise
CSS delivers ASICs tailored to the unique needs of the Industrial, Medical, Aerospace & Defense, and Consumer markets.
We adapt every design, qualification, and production test flow to meet the standards of the end application. Our system architects and design engineers optimize each solution for market-specific requirements. For example:
- Medical Devices: Ultra-low power modes, energy harvesting, and long battery life.
- Industrial Drivers and PMICs: High efficiency and robust heat distribution.
- Aerospace & Defense: Radiation tolerance, reliability, and rugged performance.
- Consumer Electronics: Compact designs optimized for cost and volume.
How We Do It
IC Design Expertise
At CSS, analog and mixed-signal circuit design is our core strength. Our world-class team averages 25+ years of IC design experience, offering unmatched expertise across multiple domains:
- High Voltage: Robust HV layouts and protection strategies for amplifiers, drivers, and switches in BCD technologies.
- Sensors & MEMS: Interfaces for resistive, capacitive, inductive, and magnetic sensors and transducers.
- Ultra-Low Power: Wireless energy harvesting, subthreshold operation, and duty-cycled modes for battery-free systems.
- Precision Analog & Data Converters: Flash, SAR, and Sigma-Delta ADCs; resistive, capacitive, and current-mirror DACs.
- Wireless Communications: LNAs, mixers, VCOs, and power amps for wide-band and sub-1 GHz transceivers.
