Overview

This analog-to-digital converter (ADC) uses successive approximation register (SAR) architecture to achieve 12-bit resolution. The ADC includes internal sample/hold circuits, a capacitive DAC, a comparator, and logic control circuits. External reference voltage is needed. The voltage reference input can be adjusted to allow encoding from smaller analog voltage span to the full 12 bits of resolution. This ADC has dual operation modes, i.e. single-ended and differential-ended. Differential-ended mode is used in high-speed and noisy environment; whereas single-ended mode is used in low-speed and clean environment. This ADC has dual speed modes, i.e., high speed and low speed, working in low speed mode could save some power. Moreover, it supports two running modes: free running and single running. In single running mode, SAR will switch to power down mode automatically so as to save power. The converter has flexible control logic, and could be easily embedded in a big system. The IP is suitable for integrated auxiliary codec applications and multi-converter architectures in wireless or battery-operated products.

Uncertainty-Guided Live Measurement Sequencing for Fast SAR ADC Linearity Testing

This paper introduces a novel closed-loop testing methodology for efficient linearity testing of high-resolution Successive Approximation Register (SAR) Analog-to-Digital Converters (ADCs). Existing test strategies, including histogram-based approaches, sine wave testing, and model-driven reconstruction, often rely on dense data acquisition followed by offline post-processing, which increases overall test time and complexity.

Three ways of looking at a sigma-delta ADC device

The growing availability of digital ICs like microcontrollers, microprocessors, and field-programmable gate arrays (FPGAs) allows developers to use complex digital processing techniques rather than analog signal conditioning. For this reason, analog-to-digital converters (ADCs) have become a widely-used component in mixed-signal circuits.

Specifying a PLL Part 1: Calculating PLL Clock Spur Requirements from ADC or DAC SFDR

In high end RF systems, such as 5G radios, the requirements are so stringent that the source of this strongest unwanted tone can be the PLL. This article outlines how spurs in the input clock to the ADC or DAC may limit the SFDR. This in turn will set the requirements for the spurs for the input clock (from a PLL), in order to achieve a specific SFDR.

Save power in IoT SoCs by leveraging ADC characteristics

Power-sensitive applications such as Internet-of-Things (IoT) require a comprehensive power savings strategy within the system-on-chip (SoC). Techniques relying solely on the use of traditional power down modes and low supply voltage may not be enough to achieve the required power targets. The analog block is often assumed to be too sensitive and not compatible with aggressive power management techniques.

High Speed ADC Data Transfer

When continuously running a high speed ADC, it can be a challenge to deal with the firehose of raw data available at the output. To use City Semiconductor’s 2.5 GS/s 12-bit ADC, for example, 30 gigabits per second of data have to be accepted.
