Fundamentals of Frequency Synthesis, Part 2: Direct Digital Synthesis (DDS)
The second of a two-part series on frequency synthesis, with an introduction to Direct Digital Synthesis. We will give a basic review of how a direct digital synthesis system works, touching on the inner workings of the DDS engine at a relatively high level. We will also discuss the tradeoffs between PLL and DDS technology as a base choice for frequency synthesis needs.Fundamentals of Frequency Synthesis, Part 1: Phased Locked Loops
The first of a two-part series on frequency synthesis, with an introduction to Phased Locked Loops. This webcast looks at the need for frequency generation, the techniques from the past present and future, and how to assess the performance of a frequency synthesis, and real world applications. Particular attention will be focused on Phase Locked Loops (PLL's) as frequency synthesizers.Low Power DDS: Benefits, Features, and Applications

Filter
Analog Filter Wizard 2.0
The Analog Filter Wizard™ helps you design a low-pass, high-pass, band-pass or band-stop filter with actual op amps. It then simulates the filter’s performance with these op amps in real time. You can ask the tool to optimize for power, noise, or voltage range, and it will pick op amps and passive components appropriately. Or you can adjust the components manually yourself.

Photodiode
Analog Photodiode Wizard
The photodiode web tool helps you select and design the best circuit for your application. To use the tool, enter the specifications of your light input, including intensity, spectral band, and the required signal bandwidth. These inputs will narrow down the available photodiode part numbers.
