An interesting question with respect to dynamic range scaling is often raised:
Does the operation of dynamic range scaling affect the SC fi lter’s frequency
response? As we learned in Chapter 3, in a typical SC circuit, an SC passive element
is used to simulate a physical resistor. Thus, if we assume that the SCF, which
undergoes dynamic range scaling, can be realized by replacing all physical resistors
in a certain RC lter with SC elements, then it is easy to fi nd that in essence the
operation of dynamic range scaling in the SCF is equivalent to multiplying all
resistance values by a scaling factor S and all c ...
