Step time for oscillator
Hi
Does anybody know why it is important for step time to be small when simulating oscillators. I was simulatiing 19.4 Mhz crystal oscillator. When my step size is 100p it does not oscillate, when it is 1ps it oscillates.
Thank You

Hi
Generally I connect the source drain and body to ground. I then give a ramp voltage say 0 to 1.2V in 1.2ps using pwl. now observe the current. I generally remains constant. C= I/(dV/dT) i.e I/(10^11). note the cap befor threshold is differernt from cap after thereshold.
gm of MOSFET
Hi
I am new here to EDAboard. I am working on 0.13u technology, I used to previously work on 0.25u technology in College. I am finding it hard to calculate the lambda of transistor(channel length modulation) . Most of my co workers do not calculate at all. I have two...
