摘要： An integrated circuit includes at least an inductive element and an active region which may include resistive, capacitive and semiconductor elements. The inductive element and part of the active region are superimposed. The integrated circuit has a screen for insulating the active region with respect to an electromagnetic field that the inductive element develops. The screen allows the implementation of inductive elements having high quality factors in integrated circuits of reduced size and in which the electromagnetic interactions between the inductive elements and the other elements are reduced.

摘要： The invention relates to a signal source (S) which comprises a local oscillator (5) for generating a reference frequency signal fo. The signal source comprises: a frequency divider by N (6) connected to the local oscillator (5) and delivering two quadratic square-wave signals (Id, Qd) at a frequency fo/N,N being equal to 2 or 4×n, and n being an integer number, and a multiphase filter (7) which supplies two sinusoidal quadratic signals (Is, Qs) at a frequency equal to m·fo/N on the basis of the quadratic signals (Id, Qd) issued by the frequency divider, m being an odd number. The invention finds its application in direct frequency conversion circuits and transmission circuits used in the field of telecommunication.
