WebSep 10, 2014 · The first-integrator will have lower gain in CIFB and while higher gain in CIFF for a given swing limit, since the first-integrator will be in the fastest path in CIFF and while slowest path in CIFB. Higher gain means lower integrating cap and hence CIFF (or faster path for the first-integrator) may be preferred from this point of view. WebCIFF: Children's Investment Fund Foundation
