The dynamic current injection, the common source node resonance,improved two order linearity performance technology, and CMOS technology being applied, an active folding Gilbert zero IF mixer with the supply voltage at 1.8 V was designed. The circuit simulation showed that at 1 MHz, the SSB noise figure of the mixer was 6. 109 dB;at 100 kHz,the SSBNF was 6.71 dB;and at I0 kHz,10. 631 dB. Frequency conversion gain was 11. 389 dB;input three order intermodulation point was 4. 539 dBm.
