well it happened once to sweep a voltage on a IC pin which had a protection diode and forgot to clamp the current to a resonable limit. guess what? the exponential I-V characteristic of the diode turned into a liniar I-V characteristic which behave like a resistence.
so i guess by damaging a...
What is the resolution of your DAC?
For IC DACs, a "current steering" topology might be helpful because you dont have cappacitors neither resistors to integrate (which consume large area) but the chip becomes larger for 12 or more bits and also the decoding circuitry becomes more complex.
The...
Your question is a little ambiguous.
If you reffer to the fact that a square signal is an infinite sum of sine signals, then decomp your square signal in Fourier Series and pick the fundamental and maybe 1st harmonic.
When designing using bjts, I think β should be considered more of a parameter the transistor came with from the fabrication process, e.g. β=100 for a npn or β=20 for a pnp. The collector current is the base current multiplied by this factor β.
On the other hand, gm is more of a parameter that...
