Özet
In this paper, a new square-root domain, first order, all-pass filter based on the MOSFET square law is presented The proposed filter 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 filter is the first square-root domain first order all-pass structure designed by using state space synthesis method in the literature The center frequency of the all-pass filter is not only attainable at megahertz frequencies but, also tunable by an external bias current The proposed filter operated 2 5 V supply voltage is constructed by current, mirrors, geometric mean circuits, a linear transconductor circuit, and a capacitor SPICE simulations are given to approve the theoretical analysis
