Abstract
A mixer includes a trans conductance unit, a gain boost unit, a mixing module and a buffer. The trans conductance unit, the gain boost unit and the mixing module cooperatively mix a differential input voltage signal pair with a differential oscillatory voltage signal pair to generate a differential mixed voltage signal pair. The buffer performs buffering on the differential mixed voltage signal pair, and has inductance that cooperates with parasitic capacitance at output terminals thereof to form an LC tank circuit that reaches resonance at a frequency of the differential mixed voltage signal pair to behave as an open circuit.
