Hey Brian,
I separately tested the device and setup in a lab with a dedicated power supply at +5 and +12V and a function generator (initial: 1kHz sine, 0.2Vpp, high impedance). With current setup (G~6), it worked perfectly, handling a signal up until around 1Vpp or so at which point as you said...
I'm thinking now it may be my FG. I'm using a laptop oscilloscope (Velleman PCSGU250) and according to the specs, the FG is 50ohm impedance, can't see an option to switch it to high impedance. Right now I'm just putting a big resistor (at least ~1Mohm) in series with the signal input (before the...
Hey Brian,
Thanks for the prompt reply, I'm both elated and dismayed you're just as baffled.
As for the "Input protection," that depends if you could clarify: does this statement mean that the difference in voltages between the inverting and noninverting pins (9 and 10 in this case) cannot...
I'm in a bind. I'm working on one of several major projects - a small radar system for my antennas class. Thing is, the hardest parts went easy, the ramp generator and active LPF. I'm on the last low-frequency part, a simple gain stage, and something is amiss.
I've attached the schematic. They...
#1 Is very hard to navigate in terms of content
#2-4 are dead links
#5 Doesn't contain information on FLLs
Can anyone explain the explicit diffences of FLLs and PLLs, especially relating to their block diagrams or how they are made (schematics, etc)?
Hey everyone
I've been scouring the internet looking for any information on frequency locked loops but it's been dismal at best. I'm not actually sure if a phased locked loop will do the same thing, but essentially I'm looking for something to automatically tune to a given frequency.
Is there...
