kinda dinky current source
This makes a precise (0.2%) 20 mA current source that can be mux'd into a 50 ohm photodiode amp input to calibrate all the downstream signal chain. I can get the LM4040 and the 125 ohm resistor both...

Low Frequency 3rd Overtone Crystal Osc
I know third overtone is used for higher frequency oscillators, mainly because fundamental are hard to make at higher frequencies. I need a 120 kHz crystal and can't find one without ordering a full...

different opamp gains based on sign?
I've got a differential signal, however, the negatives are small and intere sting while the positives are large and less interesting (but still importa nt). Is there an amplifier topology that allows...

Semi OT: Energy Star
Was "Energy Star" ever at all useful to consumers? It seems in the vein of the "Can't Enforce" logo. My guess is that manufacturers are way more scared of bad Amazon reviews these days than having to...

LDOs and output capacitors
I noticed that for LDOs which usually require a tantalum output cap to ESR-stabilize the loop, SMD chip tantalums seem to be expensive like woah, particularly in the larger values (> ~6.8uF) and more...

Rogowski transformer query
If I pass a single wire through a wound air-cored toroid with, say, 1000 turns, then that's a 1000:1 transformer. If, for convenience, I make it a 1000 turn Rogowski coil and wrap the coil around the...

RF bipolars RIP
Looks like NXP is discontinuing their SOT89 RF bipolars, like BFQ149 and BFG31 and such. Bummer. I just designed them in. They have equivalent SOT23s that they rate for 600 milliwatts. SIX HUNDRED...

OT: Dakota Pipeline Steel
Okay, we've all heard that Trump asked "who made the pipe" re: the Dakota oil pipeline, and wanted it to come only from U. S. manufacturers. So now the Left is screaming that it's made by a Russian...
