Radar generating transistor circuit?
I remember reading some while ago that LLL was working with fast switching transistors which generated "radar wavelength" signals. Then, as events go, a Georgia Tech Prof. raised a stink since he had...

process for generating "squeezed light"
Hi, How is "squeezed light" generated, for example in the GEO600 gravitational wave detector, the laser lights frequency is given more uncertainty in order to reduce the shot noise (amplitude...

[Help needed] Single supply for Instrumentation amplifier
Hello, I was spending hours today to figure out how can I use a single power supply (say 3v) to power an instrumentation amp ( I tried connecting +VCC to 3V and -VCC to ground, probably I'm doing it...

Imagined Baxandall photomultiplier power supply
This is an LTSpice-only study for a possible photomultiplier power supply. L8 and L10 are realistic - you should be able to buy them from Farnell. The transformer L1, L2, L3, L4, L5 could be wound on...

Nice Shocking! Why do they need GHz multicores? LOL
Very cheap and simple GPS display on OLED: Source code PIC18F14K22 asm (GPL): This is a EM-411 25$ or so GPS module from connected to +5V and the output to the PIC serial in. PIC is on 5V, and so is...

OT: "PUP"
The baby bird GooGull recognizes "do not pup as dg", but refuses to say anything about what "PUP" means. Naturally, it also says nothing about "DG", but it is obvious from the context that "DG" means...

Power MOSFET testing - NTE2382 N-channel
All, I have been doing some testing using the NTE2382 N-channel MOSFET for a 24V application. 1.) Test 1 - MOSFET turned off. The 24V input is connected to the drain of the FET. The gate is tied to...

Super fast sample & hold under $10?
Folks, Need to sample stuff again. Essentially an equivalent time deal like on older generation digital scopes where you have a 20MHz or so ADC and GHZ-bandwidth on the scope. Can take as long as it...

BAV199 fw recovery
Probably far fetch but anyway... I need to use some of these BAV199 for a low leakage 2nd level ESD clamp (after a nice Diode's D20V0L1B2WS low leakage but circa 30V clamp TVS. The ESD events I'm...

Delay in 3 meters of wire
Hi Guys, I have question about transit time in a wire and phase shift caused by inductance. I'm going to use 3 meters of wire and 300,000,000m/s (discuss speed later) 300,000,000m/3m =10 nanoseconds,...
