OVERVIEW
In semiconductors, the challenge has always been power versus performance.

Analog designers are faced with the challenges of designing higher-performance analog interfaces at lower supply voltages. Seamless Devices’ Switched-Mode Operational Amplifier (SMOA) provides a new class of feedback amplifiers, and addresses these issues through the application of patented switched-mode signal processing algorithms. Developed at Columbia University’s Integrated Systems laboratory, Seamless’ SMOA technology will help designers to achieve higher performance with the same power, or make the tradeoff to lower power while maintaining current performance levels, even as new process nodes continue to reduce supply voltages.

All of Seamless Devices’ ADCs offer features including:

  • High dynamic range (70dB SNDR)
  • High tolerance to clock jitter
  • Single low-power (0.9V) supply voltage
  • Power Down Mode
  • Automatic background PVT calibration
  • Available in 55nm, 40nm, 28nm, 16nm, & 14nm today
