I'm using Capture CIS 17.4. I'm trying to simulate a current sense amplifier using a part from TI. The output of current sense amplifier is showing 1.65V as per bias point display, if the same point is probed w.r.t Gnd(0) my output is 2.65V(Varying respective to my input). As per my calculation probing value is correct.
But the problem is when I'm trying to give current sense amplifier as input to my another part of circuit, it is asking 1.65V as reference (Which is actually wrong).Is anyone can give feedback/ there to help me out to resolve this issue?
It appears that you're doing a transient analysis. The transient analysis does its own calculation of a bias point to start with, using the same technique as described for DC sweep. This is necessary because the initial values of the sources can be different from their DC values. A given voltage or current source can have a different DC value and initial transient value at TIME=0. This means that the initial transient bias calculation can be different from the DC (small-signal) bias point.
