Date Published: | |
Last Modified: |
Added a new page on the uSiP Component Package.
Added a new page on Light-Dependent Resistors (LDRs).
Added data on the Early Voltage \(V_A\) and thermal voltage \(V_T\) to the Bipolar Junction Transistors (BJTs) page.
Added schematics and a design procedure for a NPN BJT current-sink whose base is driven by a resistor divider.
Added schematics and a design procedure for a BJT current mirror.
New PlatformIO page.
Updated the size codes on the SMD Electrolytic Capacitor Packages page.
Added info on the hybrid-pi transistor model to the Bipolar Junction Transistors (BJTs) page.
Added a new page on Reliability Engineering For Electronics
Added a open-loop vs. closed-loop bode plot and generalized negative feedback block diagram (with equations) to the Op-Amps page.
Added new page on the TO-99 Component Package.
Added a new page on the Thermoelectric Effect.
Added a new page on the TO-247 Component Package.
Updated the
img
shortcode so that caption text is now rendered as markdown (done by calling the hugo function| markdownify
on the passed in parameter). This allows things such as the ability to add URL links into the image caption, great when referencing the source of the image.Added a section to the Op-Amp page on Negative Impedance Converters (NICs).
Merged the Passive Filters and Active Filters pages into a single new Analogue Filters page and re-organized the entire page.
Added info on the Sallen-Key filter topology.
Added info on four common analogue filter optimizations/tunings (Butterworth, Chebyshev, Bessel and Elliptic).
Added info on overriding the standard library version of
malloc()
(and friends) with an application specific version:1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
#include <stdlib.h> int main() { int* i = malloc(sizeof(int)); free(i); } void* malloc(size_t s) { printf("My custom malloc() called"); return NULL; } void free(void* p) { printf("My custom free() called"); }
Added info on the MQTT broker Mosquitto and MQTT client Paho.
