Phase quadrature and slaved working frequency signal generator

--An in phase quadrature signal generator including a phase shifter that receives at an input terminal an input signal (Vin) supplied to phase shifting means formed of passive elements, arranged for delivering at first and second output terminals, first (OutI) and second (OutQ) in phase quadrature signals. This generator is characterised in that it further includes, between the phase shifting means and the output terminals, transconductor means having a transconductance proportional to the passive elements, arranged so as to obtain a transfer function between said first and second in phase quadrature signals independent of said passive elements.
