A quiet SEPIC negative supply
I needed to add a -3.3V to -6V supply to my RIS-796A 250A pulser, analog version. The PCB didn't have much space, so I implemented a simple inverting switcher with an LM2840 buck converter. See...

Fake product queries
I am curious as to how many (on the average) fake/phony product queries you get per month. These "queries" have a rather wide range of "sources": college departments, hospitals, construction...

Unequivalent Input Impedance in Differential OpAmp Circuit
I have an existing design that uses a single op amp stage with differential inputs and AC coupling caps on the inputs. The circuit acts as a 5:1 divi der so the two input resistors are 51 kohms and...

LTspice Zener Models
I'm looking to model a circuit with a zener diode in it and the exact part doesn't seem to have a simulation model. Looking at the 11 choices in LTsp ice I see a variety of parameters. The one that...

Speaking of high speed opamps
I'm putting together an order for some fast opamps. I've not used these yet. So.. 1.) If any have some gotcha, you know about please let me know. The circuit will be an intermediate gain stage.* (So...

Stacking MOSFETs
Is there a canonical topology to stack them in series such that one gets a switch with a higher Vds rating but maintain approximately the same switching speed?

Solder paste recommendations
Just ordered my first stencil after a hundred years with my electronics hobby and would like to find that best bang for the buck solder paste I can use. No special requirements are needed -- this is...

LC oscillator sensitivity analysis
I'm designing a 125 MHz triggered LC oscillator. It's sufficiently nonlinear that I need to Spice it in transient/time domain mode. I want to explore frequency sensitivity to component values, supply...
