Abstract

Engineering Engineering, Electrical & Electronic Physical Sciences Physics Physics, Applied Science & Technology Technology
In this paper, a 10GHz high conversion gain (normally passive mixer is loss) passive mixer is proposed. By proper sizing of LO switches and matching network, the mixer is implemented in standard 0.18 mu m CMOS technology. The mixer down-converts a 10 GHz RF frequency to an IF frequency of 1 GHz. An LO power of 0dBm is required to obtain a maximum conversion gain of 2.8dB. It is therefore possible to use the proposed mixer in a receiver without a LNA, a popular architecture in today's ultra low power communication systems.
