摘要
In this paper low power balun design is presented. It is optimized for 1.575 GHz and designed in 90 nm UMC CMOS technology. Current consumption is only 0.44 mA under 1.2 V supply voltage. The simulation shows that gain and phase imbalance are equal to 0.08 dB and 0.045 degrees, respectively. Single-ended power gain of this circuit is 2.2 dB. A special dimension matching has been made to minimize circuit susceptibility to variation of the manufacturing process.
