Abstract :
A TV-band harmonic rejection mixer (HRM) adopting a novel g m linearization technique is proposed and its harmonic rejection ratio (HRR) over the mismatch parameters is analyzed numerically using simple vector diagrams. The operational mechanism of the proposed g m linearization technique is described and its effectiveness is proved with both simulation and measurement. Based on the proposed idea and analysis, a TV-band HRM is implemented with 90 nm CMOS technology. Measurements show 3-6 dB IIP3 improvement and 37-52 dBc HRR at 29 mA current in 1.2 V supply voltage.
