hi friends
i am doing simulation using switched capacitor.
i have designed the switched capacitor integrator (delayed - non inverting)
i have donr PAC and PSS analysis for integrator ........
but when same integrator i am cascading i am getting error like zero diagonal matrix
can you suggest me how i can go for simulation of such a circuits  i have give screen shot of my error my circuit one with only integrator and one with cascaded integrator [img][/img]
