Abstract
The authors propose new switched-capacitor (SC) active-delayed block (ADB) polyphase structures for analogue finite impulse response (FIR) interpolation. Their system functions are not distorted by the input sample-and-hold filtering effect at the lower input sampling rate. Both canonic and non-canonic ADB polyphase architectures which are superior in terms of a lower speed requirement for OAs, and fewer OAs, respectively, will be proposed for SC FIR interpolators
