Abstract

In this chapter, Active filters using only OTAs and capacitors are described. Cascade design of OTA-C filters needs high input impedance for each block, as well as first-order and second-order blocks. Various structures that can be used to implement these will be discussed in detail. The subject of ladder filter simulation using component simulation as well as operational simulation also will be discussed in detail. Finally, the multiple loop feedback technique for attaining high-order filters will be considered.
