I use spectre RF for simulation.
When I simulate a mixer, the IF is set at 100kHz. So I put 900.1MHz for RF input and 900MHz for LO. But the IF is so low that everytime the simulation took a lot of time and then idled without completion. I tried changing some parameters in simulation to make it...
noise simulation
I have a question.
The simulation software I use is spectre RF.
If I want to add a noise current (say 4pA/ sqrt Hz) to the current source (1mA), How do I do this in simulation ?
I don't know the answer, but it should not be paralleling a resistor because the resistance of...
divalvs
I use tsmc .35um technology file to simulate. There exists pnp BJT symbol and layout in the library. However, in the LVS file ( or extract file ?) it can't tell there exists BJT. It means that I can't do LVS. Anyone knows how to solve this problem ? Thx
