The design of an analog-to-digital converter or digital-to-analog converter is one of the most fascinating tasks in micro-electronics. In a converter the analog world with all its intricacies meets the realm of the formal digital abstraction. Both disciplines must be understood for an optimum conversion solution. In a converter also system challenges meet technology opportunities. Modern systems rely on analog-to-digital converters as an essential part of the complex chain to access the physical world. And processors need the ultimate performance of digital-to-analog converters to present the results of their complex algorithms. The same progress in CMOS technology that enables these VLSI digital systems creates new challenges for analog-to-digital converters: lower signal swings, less power and variability issues. Last but not least, the analog-to-digital converter must follow the cost reduction trend. These changing boundary conditions require micro-electronics engineers to consider their design choices for every new design. Analog-to-Digital Conversion discusses the different analog-to-digital conversion principles: sampling, quantization, reference generation, nyquist architectures and sigma-delta modulation. It also presents an overview of the state-of-the-art in this field and focuses on issues of optimizing accuracy and speed while reducing the power level. A lot of background knowledge and practical tips complement the discussion of basic principles, which makes Analog-to-Digital Conversion also a reference for the experienced engineer.

Servo controls have evolved with respect to its size, rotational speed and its torque. Digital servos are the latest development and a step forward from the standard servo. In this article we will try to weigh the advantages and disadvantages of a digital servo against a standard servo.

To begin with, let us start with the built-in differences between the two. Both standard and digital are the same except for a microprocessor in the digital servo. This microprocessor controls the motor signals and analyzes the incoming receiver signals. A digital microprocessor is 10 times faster resulting in quicker response. Even the standing torque in a digital servo is three times than its standard counterpart. The in-built microprocessor functions processes the receiving incoming signal in a different way and in turn controls the initial power to the servomotor thereby increasing resolution and the holding power to a great extent.  Otherwise, digital servos have the same motors, gears and cases as standard servos.

Let us now understand how these digital servos operate. The built-in small microprocessor makes all the difference. It analyzes the receiver signals and then converts them into very high frequency voltage which pulses to the servo motor. Instead of 50 pulses, the servo now receives an upward of 300 pulses per second. With so many speed pulses occurring the motor will speed up and provide quicker and consistent torque.

Digital servos are the future for any model control. Anyone who has used a digital servo that fits the application would never want to return back to the standard or the analog ones. Digital servos are preferred ones because of their quality constructions, longevity and performance at an affordable price. The qualities like quick response, holding and precision power translates into quick acceleration and smooth response. Digital servos come with high performance design.

One has to agree the nothing is an unmixed blessing. In case of a digital servo the power consumption is more—the reason being that power is more frequently transmitted to servo controls. With digital servos it is always wise to install a largest capacity battery that can be accommodated.

In a snapshot a digital servo is the only solution if you need higher resolution, faster control response, increased holding power, and increased torque and even when the machine is stationery. To quote turbine display pilot Steve Elias ‘Digital servo response and precision is like flying on rails. After flying digital servos, analog versions are like handling custard.
