Technology Overview

This document details an 8-bit, 10-GHz, 8x time-interleaved Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) developed in 28-nm Complementary Metal-Oxide-Semiconductor (CMOS) technology. It features a novel design with a grouped-capacitor Digital-to-Analog Converter (DAC) and a dual-path bootstrapped switch, significantly enhancing performance and reducing power consumption.


Key Advantages

  • Threefold reduction in bottom-plate parasitic capacitance thanks to the grouped capacitors configured in a symmetrical comb structure
  • Enhanced sampling Spurious-Free Dynamic Range (SFDR) by over 5 d
  • B through the use of a dual-path bootstrapped switch
  • Signal-to-Noise and Distortion Ratio (SNDR) of 36

Problems Addressed

  • High power consumption in high-speed ADCs
  • Nonlinear capacitance affecting signal integrity
  • Limitations in achieving high precision and speed concurrently in ADC technology

Market Applications

  • Semiconductor chip applications, particularly in areas requiring high-speed and high-precision data conversion
  • Licensing opportunities for semiconductor manufacturers and technology developers
  • Advanced research and development in digital-to-analog conversion technologies
