ICsense develops custom ASICs that combine ultra-low-power performance with high precision and high reliability for battery-powered and always-on applications. Our expertise in mixed-signal and analog IC design enables energy-efficient sensing, actuation, and smart power management. With solutions like energy harvesting, low-leakage circuits, and low-power high-precision instrumentation and data converters, we help extend battery life and optimize performance.
ICsense delivers ultra-low-power mixed-signal ASICs tailored for compact, battery-constrained consumer devices. Our design approach centers on power domain optimization—partitioning analog blocks to minimize leakage, enable dynamic voltage scaling, and support aggressive duty cycling. We implement subthreshold operation, low-power biasing, and fast wake-up analog front-ends to ensure high performance with minimal energy draw. Combined with intelligent power gating and domain-specific regulation, our ASICs extend battery life without compromising functionality or user experience.
Ultra-low-power ASIC for smartphones and wearables with >12-bit accuracy, RMS noise <0.5 µT at <1 mA, wide supply range (1.6–3.6 V).
Low-power ASIC for digital MEMS microphones, featuring integrated ADC, programmable gain, and sleep mode <10 µA, for high-quality audio in consumer.
ICsense designs ultra-low-leakage ASICs that extend the lifetime and reliability of implantable medical devices. Our battery charging chips feature self-leakage below 5 nA—lower than the battery itself— ensuring minimal energy loss over time. Using advanced duty-cycling techniques, subthreshold design, and precision power management, we drastically reduce leakage while maintaining fast startup and robust performance. These innovations make our ASICs ideal for long-term, low-maintenance medical implants.
