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 →
One of the main figures of merit computed by Signal Chain Explorer is the Effective Number of Bits (ENOB) of your signal chain. In this Short and Sweet article we’ll explain how that number is computed. The ENOB value relates the Signal … Continue reading →
In the last Short and Sweet article we talked about the input and output impedances of inverting and non-inverting op-amp stages. We sort of jumped the gun a little, because we never mentioned exactly what is meant by input and output impedance. In particular, … Continue reading →
One of the unique and powerful features of Signal Chain Explorer is the ability to quickly see the input and output impedances of a stage, both “locally” (stage by itself) and “globally” (backwards or forwards to the beginning or end of … Continue reading →
In Part 1 of this Short and Sweet article we derived the formula for thermal noise as it applies to RC filter circuits: \(\displaystyle {{\eta }_{v}}^{2}={{KT}}/{C}\;\) In this blog post, we’ll try out various RC filters using Signal Chain Explorer and … Continue reading →
My Bonnie lies over the ocean. My KT lies over the C … Okay, with that lame joke out of the way, in Part1 of this (perhaps not so) Short and Sweet two-part article, we’ll derive the well-known \(\displaystyle {{\eta }_{v}}^{2}={{KT}}/{C}\;\) equation, … Continue reading →
The most recent versions of Signal Chain Explorer (SCE) have seen upgrades to the sensor stage library. SCE now has three types of sensors, all general in nature, and all meant to allow you to model a variety of basic sensor configurations … Continue reading →
This update adds the ability to specify other waveforms for HFI and EFI gargoyles (aka interferers) besides the default sine waves. You can now specify square waves, trapezoid waves, rectified sines, impulses, etc. This new specification is not fully implemented … Continue reading →
Just added a new pre-release of SCE to the website. This is a minor update that: (1) Adds a charge-source based sensor stage to the library. This allows us, among other things to model piezo sensors. We hope to have … Continue reading →
Just added a new pre-release of SCE to the website. This is a minor update that: (1) Has minor tweaks to the default settings of thermal noise charts. (2) Now models quantum effects that cause thermal noise to drop off … Continue reading →
