Summary: 
This paper presents a dual-band mixer equipped with a dual-band load using current combine technique to minimize chip area by sharing inductors for each frequency band. A systematic design methodology for the current combine load based on parasitic effect considerations is also developed. By following the proposed design procedure, the load inductance and combine capacitance for the dual-band mixer can be easily determined. A 2.4/5.2-GHz CMOS mixer design has been implemented to demonstrate the feasibility of the design technique.
