Has anyone worked with Gilbert Cells? I'm having a lot of trouble with one from ON Semi, MC1496, formerly Motorola's part, I think.
The thing is configured as a product detector. There's 2 input frequencies and they both mix down to 5 kHz. That part works well. But, the chip just happens to oscillate at 5 kHz all by itself even without the local oscillator running. Go figure. There's also a very slow moving, 400 Hz or so, modulating the 5 kHz. I cannot for the life of me, figure out where it's coming from or how to get rid of it. I appreciate any help. gene _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
