Updates This Month

Create a new page for the BJT common-collector amplifier.
Updates to the Kalman Filter page.
Upgraded the Netlify build image from Ubuntu Xenial 16.04 (which is deprecated and was going to be unsupported in November 2022) to Ubuntu Focal 20.04. This initially caused a hugo build failure, which was resolved by adding GEM_PATH to the security: exec: osEnv: section of the config.yaml.
Added info on charge pump output impedance.
Added a new page on switched-capacitor circuits.
Converted the Analogue Filters page from Asciidoc to Markdown.
Added info on Elliptic filters.
Moved the info on Sallen-Key filters into it’s own page. Added more info on low-pass and high-pass Sallen-Key filters, along with simulated examples and info on their high-frequency limitations.
Moved the PCB Design->PCB Manufacturing And Assembly Considerations page to Electronics->Circuit Design->The Schematic And PCB Design Guide.
Added a new page on Switched Integrator ICs.
Updated the C++ On Embedded Systems page with more info and examples on what C++ features you should and shouldn’t use in an embedded system. Also replaced a code example that was using a pointer to use a reference.
