A novel square-root domain realization of first order all-pass filter

In this paper, a new square-root domain, rst order, all-pass lter based on the MOSFET square law is presented. The proposed lter is designed by using nonlinear mapping on the state variables of a state space description of the transfer function. To the best knowledge of the authors, the lter is the rst square-root domain rst order all-pass structure designed by us..
