Mixed Signal & Analogue

While digital electronics tends to get more than its fair share of coverage, analogue electronics remains the technology that makes things happen. It’s the interface between the real world and the 1s and 0s of the digital domain.

The range of technologies falling into the analogue domain is wide; everything from data conversion to amplification to switches. Like electronics in general, analogue products are getting more complex as device developers look to integrate more functionality. Recognising this, manufacturers have started to develop more capable design tools to support engineers.

Because analogue design is so important, New Electronics covers all aspects of the technology regularly.

How to get all the codes from your high performance SAR a/d converter

You might have specified an 18bit SAR a/d converter with a signal to noise ratio (snr) of more than 101dB, but will your design give you the performance you expect? To achieve that dynamic range, you need to make sure your largest signals use the converter's full scale; in other words, you need to exercise all the codes. But how do you do that?

Selecting precision op amps for sensor input processing designs

As one of the basic building blocks used in an array of consumer, industrial, scientific and other applications, the operation amplifier (op amp) is amongst the most widely used electronic devices. For most low end applications, the requirements are straightforward and choosing the appropriate device is relatively easy. However, selecting the optimal precision op amp for higher end sensor input processing designs can provide system designers with a challenge.

EV battery management essential for desired lifetime and charge cycles

For hybrid (HEV) and full electric vehicles (EVs), Li-Ion batteries offer the best trade off of power, energy density, efficiency and environmental impact. But Li-Ion batteries can be delicate and dangerous, while automobiles can be cruel and unforgiving. The challenge is to bridge the gap between the two environments.

Programmable mixed signal device looks to mop up utility functions

In the mid 1990s, there was a flurry of activity as companies attempted to emulate the success of the fpga in the analogue world. These programmable analogue parts, for a number of reasons, failed to capture the interest of electronics designers. Since then, Cypress has had particular success with its PSoC range, which integrates analogue and digital peripherals, memory and a microcontroller on the one chip.

Manufacturers continue to develop the analogue ‘building blocks’

During New Electronics' Analogue Roundtable last month, the discussions focused on a number of areas. One was the increasing complexity of analogue components; another was their increasing functionality. But the participants also underlined the need for device developers to continue to develop what they called the 'building blocks' of analogue design.

New approaches to a/d conversion technology

Advances in architecture and integrated circuit design techniques have allowed a/d converter manufacturers to push sample rates, resolution and power consumption. In so doing, they have simplified development of many systems while enabling the next generation of others.
