Switched-Mode Signal Processing

Analog design in the time-domain

  • Signal information encoded only in pulse-widths

Near-supply analog operation

  • Signal swing only depends on width of pulses

Improves with CMOS scaling

  • Transistors get faster with scaling

*US Patent #10075133B2: Systems and methods for ring-oscillator based operational amplifiers for scaled CMOS technologies

SMSP enables high-performance mixed-signal design in scaled CMOS

Our products – Highly integrated chips and ADC IP

Next-generation ADCs

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 advantages

Using 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

Oversampled architecture

Resistive input, easier to drive
