Abstract :
In this paper, a novel low-power current-reused folded cascode harmonic rejection mixer (HRM) for digital video broadcasting-terrestrial (DVB-T) tuner application is proposed. In proposed architecture, by adopting current-reused folded cascode topology, linearity of the HRM is improved and the low-power implementation is realized. In the frequency range of 48~862 MHz, simulation results of the proposed HRM show 41.1~41.5 dB 3rd-order harmonic rejection ratio, 6~9.9 dB voltage gain, 10.9~11.3 dB NF, and 5.3~9.8 dBm IIP3, while drawing 1.5 mA current from a 1.2 V supply in a standard 0.13 um CMOS technology.
