SCE Lesson 1 – Building and Analyzing Your First Signal Chain

Robust Circuit Design Posted on November 13, 2017 by adminNovember 13, 2017

Introduction The main purpose of Signal Chain Explorer’s (SCE) is to quickly build a signal chain and explore how interferers degrade the signal to noise ratio.  With that in mind, in this lesson we’ll build a simple signal chain and … Continue reading →

Noise distribution considerations for a multi-stage audio amplifier

Robust Circuit Design Posted on February 27, 2017 by adminNovember 13, 2017

In this article we investigate how thermal noise and thermal distortion play a part in the design of a phono audio signal chain. For our example, we’ll use a Shure M97XE cartridge, a 47K/200pF termination shunt, three gain stages of 10X … Continue reading →

Version 0.971 of Signal Chain Explorer Uploaded

Robust Circuit Design Posted on February 27, 2017 by adminFebruary 27, 2017

As mentioned in the last post, we’ve been busy adding functionality to handle differential signal stages to Signal Chain Explorer. This stuff isn’t ready yet, but in the course of our work we uncovered a math error in one of … Continue reading →

Differential Signals Preview

Robust Circuit Design Posted on January 25, 2017 by adminJanuary 29, 2017

We’ve been hard at work the past few months figuring out how to add differential signal stages to Signal Chain Explorer.  An example of a signal chain using differential signals is given above.  Here, we have a microphone or acoustic pickup signal … Continue reading →

Required Sensor Power – Part 3

Robust Circuit Design Posted on November 29, 2016 by adminNovember 30, 2016

In Parts 1 and 2 of this series on required sensor power we introduced you to the formulas needed to compute this power, and you got to see the formulas in action in Signal Chain Explorer. At the end of … Continue reading →

Required Sensor Power – Part 2

Robust Circuit Design Posted on November 26, 2016 by adminNovember 29, 2016

In Part 1 of this Short and Sweet article we introduced the concept of finding the minimum required power a sensor needs to deliver in order to achieve a desired signal quality for a given signal chain — that quality being … Continue reading →

Required Sensor Power – Part 1

Robust Circuit Design Posted on November 21, 2016 by adminNovember 29, 2016

New functionality was recently added to Signal Chain Explorer that computes the minimum sensor power required to achieve a desired SNR (or ENOB) for a particular signal chain. This feature was originally experimental, but it didn’t take us long to decide to include … Continue reading →
