description | Novel l ow-voltage first-order and second-order square-root-domain all-pass filters
derived systematically by means of transfer function decomposition and state -space synthesis
techniques are proposed. The employment of only a few geometric-mean cells and grounded
capacitors permits the circuits to absorb shunt parasitic capacitances, which is desirable for
production in monolithic form . The circuits enjoy the features of electronic adjustment of
frequency characteristics, wider dynamic range and low-voltage environment operation. The
filters are employed to design high-order all-pass filters using cascade approach. First-order
low-pass and second-order band-pass filters, being the inherited building blocks of the
proposed low-order all-pass filters are also discussed. The behaviour of the filters is
evaluated through simulations using Taiwan semiconductor manufacturing company 0.25 μm
level-3 complementary metal oxide semiconductor process parameters, where the most
important performance factors are considered. |
