Abstract
An IQ mixer and a method thereof. The IQ mixer comprises a pair of Gilbert cells and a degeneration inductor. Each pair of Gilbert cells comprises a pair of first current generators and a pair of switching networks. The pair of first current generators converts an RF signal pair to currents respectively. The pair of switching networks, coupled to the first current generator, modulates the converted RF signal pair with an oscillation signal pair to generate a mixed signal pair. The degeneration inductor is coupled to all pairs of the first current generators, such that it is shared by the pair of Gilbert cells.
