Hi,
This is regarding the offset error of a Pipeline ADC (9 bits) with sign bit.
Generally offset shifts the entire output transfer curve, hence doesn't change the shape of it and also the code width.
I have few questions:
1). Is there any upper limit for the offset value? If yes, then does...
floating node can cause the unwanted voltage of any node which can cause the convergence issue. Therefore, problem in simulation that will say that no dc solution due to the convergence issue. Spectre dose it automatically by some method.
Re: HSPICE or SPECTRE
I think HSPICE is not a GUI interface. we have to generate the netlist from the schematic and import the netlist and after that we need to run the simulation where as Spectre is a GUI interface. But it is also possible to run spectre in commannd prompt. It is always best...
