Resistive mixers for reconfigurable wireless front-ends

Two resistive mixers realized in a 0.13 /spl mu/m CMOS process are presented. The mixers are designed for implementation in a reconfigurable mobile terminal that supports the WCDMA mobile phone standard and the IEEE 802.11a and HIPERLAN/2 WLAN standards, respectively. The mixer design process, as well as simulated and measured results, are given and discussed. The entirety of properties and performance makes these mixer types very attractive for reconfigurable architectures.
