Entitled: "SPICE simulation goes awry?",
Wrote the following:
|I'm running some tests on a selection of circuits supplied with this
|version of spice I'm currently trying out. I've noticed that when I
|run a TA on a 7Mhz Colpitts oscillator with a 1v supply rail WRT GND
|(this is the specified value in the schematic although it seems
|*bloody* low to me) I get a steadily increasing output signal sine
|wave of well over 13volts (and it's *still* climbing by the time I get
|fed up watching it). How can this possibly be right? It's hardly
|likely in the real world (even with my scope:-)).
Please post the schematic.
