High-Speed, Real-Time Recording Systems
In today's world of high-speed A/D converters operating in the gigahertz range, real-time signal recording has become a challenging task. When designing a real-time recorder capable of streaming sustained data to disk at rates of up to 2 GB/sec and higher, the developer has to consider the limitations presented by the operating and file systems, disk drive technology, the hardware interfaces, and the RAID controller technology. This handbook describes some of the features that are widely desired in such a system, including the use of a non-proprietary file system and the use of a client-server architecture.

Complete High Speed, High CMRR Precision Analog Front End for Process Control
Signal levels in industrial process control systems generally fall into one of the following categories: single-ended current (4 mA-to-20 mA), single-ended, differential voltage (0 V to 5V, 0 V to 10 V, ±5 V, ±10 V), or small signal inputs from sensors such as thermocouples or load cells. Large common-mode voltage swings are also typical, especially for small signal differential inputs; therefore good common-mode rejection is an important specification in the analog signal processing system.

1ppm Settling Time Measurement for a Monolithic 18-Bit DAC
Performance requirements for instrumentation, function generation, inertial navigation systems, trimming, calibrators, ATE, medical apparatus and other precision applications are beginning to eclipse capabilities of 16-bit data converters. More specifi cally, 16-bit digital-to-analog converters (DACs) have been unable to provide required resolution in an increasing number of ultra-precision applications. New componentshave made 18-bit DACs a practical design alternative1. These ICs provide 18-bit performance at reasonable cost compared to previous modular and hybrid technologies. The monolithic DACs DC and AC specifi cations approach or equal previous converters at significantly lower cost.

Interfacing high-voltage applications to low-power controllers
A common requirement of industrial applications is to interface high-voltage potentials, such as signal outputs of sensor switches and AC rectifiers, to the peripheral input ports of low-voltage MCUs and DSPs. A new generation of interface circuits providing this function are digital-input serializer (DIS) devices. This paper explains the functional principle of a DIS and its configuration in a typical industrial interface design.

Microwatt “Always On” Analog Measurement Circuits for Solar Power Applications
From large panels to harvested microwatts from a few photodiodes, solar power is increasingly prevalent in autonomously-powered systems. In low-power solar systems, it may be critical to assess whether there is sufficient sunlight at a given time to power the system. In some cases, there may be not even sufficient power to wake the microcontroller. Learn how with some simple analog circuits that an ultra low power op-amp-perfect for critical "always on" supporting circuitry around the microcontroller-can be used.

Considerations for Bulk CMOS to FD-SOI Design Porting
The scope of this study is to examine the efforts required for a straight “port” of an existing bulk CMOS design to FD-SOI at the same node. The objective would be to get value from FD-SOI for a modest redesign effort – even if this means not necessarily taking maximum advantage of the potentialities of FD-SOI. The focus is on FD-SOI with Ultra-Thin Buried Oxide. This document intends to be sufficiently generic to be applicable to different possible implementations of the FD-SOI technology by foundries.
