Making the most of the System Level in Analog Design
There is a disconnect in Analog IC Design. A separation between system level and implementation level design activities has crept up on us. The analog world seems to have evolved into two realms: equations and spreadsheets on one side; netlists, polygons and Spice on the other. It is like a split between the right brain and the left, leaving us struggling to combine technology with art.

What the Nyquist Criterion Means to Your Sampled Data System Design
A quick reading of Harry Nyquist's classic Bell System Technical Journal article of 1924 does not reveal the true significance of the criterion which bears his name. Nyquist was working on the transmission of telegraph signals over a channel that was bandwidth limited. A thorough understanding of the modern interpretation of Nyquist's criterion is mandatory when dealing with sampled data systems. This tutorial explains in easy to understand terms how the Nyquist criterion applies to baseband sampling , undersampling, and oversampling applications.

Implementing a variable-length Cat5e cable equalizer
Unshielded twisted pair (UTP) cables have long been used to transmit data over long distances, starting with telephone line networks. All UTP cables attenuate the signal over frequency with maximum attenuation at maximum signal frequency. This attenuation will also increase as the cable length increases. This application note focuses on a continuously-adaptable equalization technique of Category-5 enhanced (Cat5e) cable for applications intended to be used with various length of Cat5e cable.

Fundamentals of Sampled Data Systems - Overview
In this application note, a typical DSP sampled data system is explained. There are two key concepts involved in the actual analog-to-digital conversion process: discrete time sampling and finite amplitude resolution due to quantization. An understanding of these concepts is vital to DSP applications.

Fundamentals of sampled data systems
Analog-to-digital converters (ADCs) translate analog quantities, which are characteristic of most phenomena in the "real world," to digital language, used in information processing, computing, data transmission, and control systems. Digital-toanalog converters (DACs) are used in transforming transmitted or stored data, or the results of digital processing, back to "real-world" variables for control, information display, or further analog processing.

Capacitive TurboSensing (CTS)
This article describes patent-pending CTS (Capacitive TurboSensing) approach. Capacitive systems monitor e-field environment using typically front-end capacitive sensors to estimate human finger proximity from the capacitive touch interface. Innovative on-chip CTS algorithm is ready to coexist with custom code on Freescale platforms and perform safe and fast capacitive measurement based on guaranteed CTC (Capacitance-to-Time-Conversion).

Thermocouple Circuit Using MCP6V01 and PIC18F2550
This application note shows how to use a difference amplifier system to measure EMF voltage at the cold junction of thermocouple in order to accurately measure temperature at the hot junction. This can be done by using the MCP6V01 auto-zeroed op amp because of its extremely low input offset voltage (VOS) and very high common mode rejection ratio (CMRR). This solution minimizes cost by using resources internal to the PIC18F2550, such as 10-bit ADC and 4-bit adjustable reference, to achieve less than 0.1°C resolution from a measurement range of -100°C to 1000°C.

How to Create a Touchless Slider for Human Interface Applications
Imagine being able to control electronics products at home and in the office, not with a direct touch but with the sweep of your hand. Advanced "touchless" human interface technology is now within the realm of practical implementation, even for products as commonplace as the alarm clock beside your bed. We all have experienced the frustration of locating the snooze and silence buttons on an incessantly beeping alarm clock at 6:00 a.m. What if you could extend your sleep just a bit longer by simply waving your hand or tapping a virtual button to shut off the alarm without fumbling to find the clock in the dark?

Powering High-Speed Analog-to-Digital Converters with Switching Power Supplies
This article demonstrates that analog-to-digital converters can be powered directly from switching power supplies with no loss in performance if careful design practice is followed. The converter's performance showed no degradation when powered from the ADP2114 switching supply versus ADP1708 linear supplies. Using a switching power supply can improve supply efficiency by 30 to 40 percent and significantly reduce overall power consumption-even more than simply selecting a lower power converter. In many systems these devices are running continuously, so employing switching power supplies results in significantly lower operating costs with no penalty in performance.
