Embodiment Construction
[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0027] Such as figure 1 As shown, the mixer based on current multiplexing technology includes a transconductance stage circuit 1, a switch stage circuit 2 and a load stage circuit 3; the transconductance stage circuit 1, switch stage circuit 2 and load stage circuit 3 are connected in sequence; The transconductance stage circuit 1 adopts a current multiplexing structure and a source degenerate inductance structure;
[0028] The transconductance level circuit 1 is used to access the radio frequency voltage signal, convert the radio frequency voltage signal into a radio frequency current signal, and repeatedly use the radio frequency current signal;
[0029] The switch level circuit 2 is used to access the local osci...
