Ultra-Low Voltage 10-bit SAR ADC ID: 2020-015

An innovative 10-bit 5-kHz SAR ADC designed to operate at an ultra-low supply voltage of 0.2 V, optimizing power efficiency.

Technology Overview

This technology introduces a groundbreaking 10-bit Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) that operates on an ultra-low supply voltage of 0.2 V. It incorporates dynamic bulk biasing and an ultra-low-supply-voltage comparator to overcome the inherent speed-noise trade-off and variability in subthreshold circuitry due to process-voltage-temperature (PVT) conditions. The ADC showcases exceptional improvements in speed, power efficiency, and yield, making it a pivotal development in low-power electronics.

Key Advantages

• Operates on an ultra-low supply voltage of 0
• 2 V, significantly reducing power consumption
• Incorporates dynamic bulk biasing to maintain circuit functionality amidst PVT variations, nearly doubling the yield under variable supply conditions
• Features an innovative comparator design that achieves over threefold speed improvement with minimal noise penalty

Problems Addressed
