Switched-capacitor interpolators without the input sample-and-hold filtering effect

The authors propose new switched-capacitor (SC) interpolators whose frequency responses are no longer affected by the input sample-and-hold filtering effect which occurred in previous circuits. Two different types of architectures are discussed, one for input sampled-and-held signals, and the other for arbitrary input signal formats. Examples are given to illustrate both types of SC interpolator circuits.
