but spelling is not
Precision timing is critical to all connected embedded systems, from the board level to the network to the cloud, as all those involved must be synchronized.

Fun with spherical cows
So I have this gig coming in to build charge amps for a French ion accelerator lab. The specs are for 1 kHz - 60 MHz, ideally less than 0.3 nV/sqrt(Hz) noise, when hung off a detector using 250-mm...

Re: Fastener choices
If I had a vote, I say make it easy to take apart as something will go wrong - sooner or later. Unless this is meant to be tossed when it dies! John :-#)#

clamp diodes
Assume we have a 1-ohm 2512 current shunt resistor that we don't want to fry. My thought is to put a pair of big diodes across it to limit the current. The associated ADC will be maybe +-250 mV full...

Re: Boot from RAM feature
This is not a new idea. the only way to get an 80286 out of protected mode was a hard reset. usuing a virtual machine is probably easier.

OT : Relativity Q
I'm in a spaceship travelling at 0.866c away from Earth. AIUI, that's a time dilation of 2, and my speedometer, which of course uses my on-board clock and a set of mile markers laid down by a previous...

Re: LC oscillator using BUF602
Perhaps. Neither inductor has any parallel capacitance, and L2 hasn't got any series resistance either. Replacing L1 with a 150n Wurth ferrite bead, which does come with full set of data - the part I...

Re: a little oscillator theory
I read somewhere that to get the lowest possible phase noise, the gain element should be cut off for most of the cycle while the tank freewheels. Once per period, it should give a little kick at the...
