Electronics Forum / CAD / November 2005Circuit Contest - Last Day
Monday, October 31, is the last day for submission to the first circuit analysis/design contest. So far only two reasonable submissions for Circuit1. None for the others. No surprise.

(;-) Besides there are a number of people here who aren't Merkans. The thing with orange flesh is only called a swede in England, I think In Scotland, it's a turnip or neep. I'm not sure what if any difference there is between a rutabaga and a turnip or swede. Mangold-wurzel, anyone? That 'wurzel' is German or Dutch in origin, I'll bet. >>Both; it's a PUN (check - Czech, Swede - swede). Geddit? > >I'm afraid I got it the first time. You should have subtly signalled that, then.

There's turnips, there's kohlrabi, and there's rutabaga, and as you go down the density scale, there's carrots, and wood. You can bite into a kohlrabi, almost as easily as you could bite into a potato, or an apple. And, heh, heh, the flavor of a kohlrabi is kind of "sweetish". Guh-hyuk! <rimshot>. A turnip is only a fat albino carrot. But a rutabaga - now, that's the yellow one - I've never seen a rutabaga that's as orange as a carrot, but biting into one would be like biting into a carrot that's covered with wax and has a radius of about 3" (7.5 cm). To make a rutabaga edible, you have to cook it for about an hour. But, DAMN! They're tasty! They have that "adult" flavor, like Brussels sprouts. Gotta go make some lunch now. ;-) Cheers!

Now that was a useful link. After quickly examining (about 10 ~ 15 minutes) the circuits involved; #1 is a buffer while not necessarily slower than an old LH0002 most certainly has higher input impedance. #2 Looks like a multiplier/divider circuit of the form X*Y/10Z where X and Y are bipolar (four quadrant) and unipolar Z. #3 looks like a differential to single ended BiCmos IF amplifier with AGC. Very useful for SSB and ISB systems. Is that anywhere near close? SignatureJosephKK >>>Andrew Holme wrote... >>>> [quoted text clipped - 39 lines] > >Is that anywhere near close? Nope.

I think you could have upped the quality of the contest by asking how does this circuit improve or achieve this or that performance, instead of asking for basic functionality like differential receiver, opamp, and that double buffered thing with what is probably shoot thru control. >>>> You might not have many responses, but I'm sure I'm not the only person >>>> waiting to be enlightened, whose curiosity was aroused by one or other [quoted text clipped - 20 lines] > for basic functionality like differential receiver, opamp, and that > double buffered thing with what is probably shoot thru control. Okay- I took it to be a receiver with that RS485-like notation INN and INP, threw me- it is a comparator then. >>>>> You might not have many responses, but I'm sure I'm not the only person >>>>> waiting to be enlightened, whose curiosity was aroused by one or other [quoted text clipped - 23 lines] >Okay- I took it to be a receiver with that RS485-like notation INN and >INP, threw me- it is a comparator then. All three circuits are portions of a HUGE chip, the largest I've ever designed, 10.0mm X 10.5mm I thought I had mentioned that before. &nb |
