Abstract
A high-pass filter includes at least one circuit unit constituted by a first branch and a second branch both connected to an input of the filter on one side and, on the other side, to an adder the output of which is the output of the filter. The first branch includes means for transferring an input signal substantially without modifying its frequency content, and the second branch comprises a low-pass filter. The circuit elements are chosen such that the components of the input signal with frequencies below the cut-off frequency of the low-pass filter are substantially cancelled out at the output of the adder. The filter is suitable for being produced within a particularly small area in an integrated circuit.
