Method for realising an electronic circuit having a desired filter transfer function and electronic circuit architecture for realising such a filter transfer function

摘要

Electronic circuit (F) including input terminals (IN1,IN2) and output terminals (OUT1, OUT2) between which a desired filter transfer function (F(s) )is realised by said electronic circuit when an input signal is applied between said input terminals (IN1,IN2) is characterised in that said electronic circuit (F) includes at least one first passive series element (Z1) having a first series impedance, a first terminal of which is coupled to one of said input terminals (IN1), a second terminal of which is coupled to one of said output terminals (OUT1), said electronic circuit further including an active circuit (G) coupled between said output terminals (OUT1,OUT2), and including a filter circuit (H) with a filter transfer function (H(s)) such that said desired filter transfer function (F(s)) is obtained.
