In phase quadrature and slaved working frequency signal generator
An in phase quadrature signal generator including a phase shifter ( 1 ) that receives at an input terminal ( 2 ) an input signal (Vin) supplied to phase shifting means ( 3,4 ) formed of passive elements, arranged for delivering at first and second output terminals, first (Out_I) and second (Out_Q) i...

| Zusammenfassung: | An in phase quadrature signal generator including a phase shifter (
1
) that receives at an input terminal (
2
) an input signal (Vin) supplied to phase shifting means (
3,4
) formed of passive elements, arranged for delivering at first and second output terminals, first (Out_I) and second (Out_Q) in phase quadrature signals. This generator is characterised in that it further includes, between the phase shifting means and the output terminals, transconductor means (
11, 12
) 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. |
