Embodiment 1
[0025] The direct conversion radio frequency receiving front-end circuit device proposed by the embodiment of the present invention can be regarded as the structural integration of the source degenerated low noise amplifier and the active mixer. The module structure diagram of the device is as follows figure 1 As shown, it includes a driver stage circuit 1 , a switch pair circuit 2 and a load circuit 3 .
[0026] The schematic diagram of the circuit structure of the above-mentioned direct conversion radio frequency receiving front-end circuit device is as follows: figure 2 As shown, the specific driver stage circuit 1 is used to connect with the switch pair circuit 2, including NMOS transistors M1-M6, which convert the small signal voltage vRF into a small signal current iRF, and the small signal current iRF is converted through the NMOS transistors. The signal current iRF is folded and flows into the source of the PMOS transistor in the switch pair circuit;
