The figure below is the differential output of a switched-capacitor integrator. The input is a 1 mV sine wave: 1m×sinωt. Theoretically the output should be 16m×(1 - cosωt) but it is 16m×(0.5 - cosωt) i.e. it has a 8 mV negative offset and I don't know why? The sampling frequency is 62.5 KHz and the integrator structure is the conventional one.
Hi LvW,
Thanks for your reply. The integrator circuit is a conventional one like this:
Could you please explain what are these structures and that this circuit is which one?
Thanks.
