Method in order to form the output signal by mixing the receiver and the input signal which have the mixer circuit and the mixer circuit with the oscillograph signal

摘要

This invention regards the method of mixing the receiver, and the input signal which have the mixer circuit and the mixer circuit with the oscillograph signal. The input signal which the mixer circuit 300 which relates to this invention, 1st input node 301 in order to receive input signal Vin and 2nd input node 302 and, in 1st output node 321 and 2nd output node 322 and voltage - electric current conversion expedient R1a, R1b, R2a, R2b and each other and 1st input node 301, 2nd input node 302, switching expedient M1, M2, M3 and M4 which operational are connected and, has in 1st output node, 321, and 2nd output node 322 is mixed, 1stOutput node in 321 and 2nd output node 322 it forms according to the oscillograph signal. Voltage - electric current conversion expedient R1a, R1b, R2a and R2b have, 2nd voltage - electric current converter R1b in order to form 1st voltage - electric current converter R1a in order to form in 1st switching node 311 1st electric current, and in 3rd switching node 313 3rd electric current, according to input signal Vin and R2a and, in 2nd switching node 312 2nd electric current, and in 4th switching node 314 4th electric current, according to input signal Vin and R2b and. As for switching expedient M1, M2, M3 and M4, between 1st phase 1 of the oscillograph signal, 2nd switching node 312 is formed, in order in 2nd output node 322, to connect 3rd switching node 313, to 1st output node 321, between 2nd phase 2 of the oscillograph signal, 1st switching node 311, in 1st output node 321, 4th switching node 314, to connect to 2nd output node 322. As a result, 1st and 3rd switching node 311,313, is respectively separated from 2nd and 4th switching node 312,314. This prevents the crossover distortion which minds, each switch M2 from the parasitic capacitance which it is related with 1st and 3rd switching node 311,313 and M4 when it is opposite, in the same way, prevents the crossover distortion which minds, each switch M1 from the parasitic capacitance which it is related with 2nd and 4th switching node 312,314 and M3.
