Hi. I am simulating the switch capacitor circuit to realize a resistor (say). The operation is as follows: On phase phi1, V1 is sampled across capacitor C. The next overlapping phase phi2, V2 gets sampled. The difference of these voltages causes the current flow. Its all quite simple.
When I simulate with all the ideal components in spectre, I get current spikes at the switching time instants. In books it is said that average current will flow between V1 and V2. Now my question is how to find this average current. There are just spikes of current (these spikes, I assume, are perfectly fine).
My actual aim is to use this switched cap resistor inside a continuous time circuit to say bias point of something. So that when switching frequency increases I will get higher current.
Regards,
