Abstract :
A Ka-band lumped element Dual-Behavior Resonator (DBR) filter in 0.13-μm CMOS is presented. The DBR filter consists of Dual-Behavior Resonators (DBRs) and inverters connecting the DBRs. The inverters and the DBRs, which define the stopband transmission zeros, are realized by CMOS spriral inductors and metal-insulator-metal (MIM) capacitors. A second order DBR filter with two transmission zeros is designed and fabricated in standard 0.13-μm CMOS technology. The measured filter has a 3-dB bandwidth of 15% at the center frequency of 27.8 GHz. High rejections larger than 48 dB are realized at the two transmission zero frequencies of 20.2 GHz and 37 GHz.
