Abstract :
The authors present a set of direct implementations of lattice filters using switched capacitor techniques. They discuss both FIR (finite impulse response) and AR versions of the lattice topology. The circuits described possess all the properties of their digital counterparts such as designing directly in the digital domain and exhibiting a uniform cascade of identical sections; hence they are readily applicable to VLSI implementation. Furthermore, they are completely stray insensitive. The feasibility of the approach has been confirmed by two discrete prototype filters
