This noise is also generated in feedback signals from Rs which may therefore causes the comparator to malfunction. To prevent chopping malfunctions, r 5(r 6 ) and C 3(C 4) are added in order to act as noise filter. However, when the values of these constants are increased, the response from Rs to the comparator becomes slow. Hence, the value of the output current lo is higher to some extent than the computed value.
