Abstract

Abstract

This paper deals with the design of switched-current (SI) high-pass ladder filters using a novel bilinear/feed-forward differentiator (BFD). The BFD is based on SI modular block, the generalized differentiator(GD) proposed in this paper. Various differential functions can be performed by the GD. Two different design techniques employing S domain and Z domain frequency transformations are described respectively. Examples of Chebyshev and Elliptic high-pass filters are also given.
