Abstract
This paper presents a broadband Gilbert low noise mixer implemented with noise cancellation technique operating between 10 MHz and 0.9 GHz. The Gilbert mixer is known for its perfect port isolation and bad noise performance. The noise cancellation technique of LNA can be applied here to have a better NF. The chip is implemented in SMIC 0.18 μm CMOS technology. Measurement shows that the proposed low noise mixer has a 13.7-19.5 dB voltage gain from 10 MHz to 0.9 GHz, an average noise figure of 5 dB and a minimum value of 4.3 dB. The core area is 0.6 × 0.45 mm2.-
