Analog, Digital, and RF circuit design

At the heart of nearly every product being manufactured in the consumer or industrial arena, a green printed circuit board containing hundreds of resistors, capacitors, and IC’s is hard at work implementing the functionality that the product was designed for. Our core competence is the design of this circuitry.

Many folks ask, “since we live in a digital age, why do we need any analog circuitry on our board?” This is a good question, with an equally sound answer: simply put, we live in an analog world. The world of digital is a realm of binary 1’s and 0’s, on or off. The analog world we live in contains much more than on or off, with an infinitely varying array of speeds, colors, temperatures, and so on. Therefore, though the heart of a printed circuit board’s circuitry is a digital microprocessor, it must be connected to the analog world we live in so that its efforts can be given meaning. This is done with an assortment of analog-to-digital converters bringing information from our world into the microprocessor, of digital-to-analog converters taking computer information and re-constituting it into a human-readable format, as well as numerous analog-realm components designed to complete the interface to items such as speakers, motors, LCD screens, and so forth.

Analog circuit design is not a new profession. For many decades, engineers have designed the analog circuitry inside the products we use. As new technologies have arisen, designers have had new analog components to make use of. Today, there are thousands of analog devices to choose from, each having their own unique physical and electronic characteristics.

eLab Digital Engineering succeeds by bringing together a combination of know-how, gained from years of experience in designing analog circuitry, as well as modern computer-based analog design tools capable of simulation analog circuit behavior under a variety of conditions. The end result is a solid, reliable interface through which the digital microprocessor can interact with the end user.

The past two decades have brought many changes into the electronics design industry, not the least of which is the proliferation of a wireless, or RF (radio frequency) link. This technology is not new, but its refinement into miniature, handheld circuitry has launched a wave of wireless consumer and industrial products. On the consumer side, handheld phones have grown into mobile internet terminals, capable of high-speed wireless data links drawing very little power from a battery. On the industrial side, new topologies such as mesh network have enabled sensor networks to enter places previously unattainable by earlier technologies.

We commonly receive requests for wireless functionality in development of a new product, and are happy to oblige. Wireless circuitry allows for unique product functionality such as a vending machine requesting a soda refill or an over-the-road refrigerated tanker reporting a temperature problem, and with today’s technologies a reliable wireless link can be constructed at a very reasonable price point.
