Our products – Highly integrated chips and ADC IP
Our first generation of products is for the medical imaging and 4G/WiFI markets. We have silicon-proven devices from TSMC’s 28nm HPM process and test results are available under NDA. Our next generation of products is geared for the high bandwidth requirements needed for LIDAR, 5G wireless, and G.fast communication systems. We also have basic IP available such as bandgap references and LVDS drivers.
SMI Si-proven ADC advantagesUsing continuous-time sigma-delta ADCs reduce system cost as it relaxes the anti-aliasing requirements. In addition, because of the input being resistive instead ofcapacitive like most ADCs, it lowers the power requirements of the input buffer. Also, our ADCs are able to tolerate a lot of clock jitter which allows the system designer to use less-costly PLLs for clock generation.
SMI ADCs lower system cost
Single voltage supply operation
Robust jitter tolerance
Resistive input, easier to drive
