A compact 5GHz Q-enhanced standing-wave resonator-based filter in 0.13μm CMOS

A fully-integrated 5 GHz bandpass filter with 0 dB IL and 3 dB bandwidth of 9.5% (1 dB bandwidth of 6%) is reported. The filter employs novel on-chip capacitively-loaded, transmission-line standing-wave resonators and Q-enhancement circuits. A prototype 5 GHz on-chip filter, implemented in 0.13 mum CMOS, dissipates 2.88 mW from a 1.2 V supply, and occupies a die area of 0.3 mm
