Abstract :
A systematic method for the simulation of LC ladders and unit element filters by means of switched-capacitor (SC) circuits is proposed. The method is based on the use of wave equivalents of various two-port subnetworks which are now realized by the same type of SC symmetric subcircuits. These subcircuits serve as the structural unit blocks for realizing high-order circuits. Parasitic-free modular circuits of practical interest can be developed. Examples of high-order circuits are given. It is concluded that this wave method is simple in its concept and also in the circuit design.<>
