Abstract:

© 2020 Institution of Engineering and Technology. All rights reserved. On-chip passive distributed-element-based bandpass filters (BPFs) usually provide a decent stopband suppression across a limited bandwidth. To solve this drawback without adversely affecting other performance metrics, a simple but effective miniaturised BPF design approach is presented in this work. The proposed integrated BPF topology uses a combination of a coupled-inductor structure with a pair of metal-insulator-metal capacitors in a quasi-lumped-element realisation. To show the operational principles of this BPF approach, a simplified inductor-capacitor-equivalent circuit model is used for its theoretical analysis. From this analytical framework as an initial design guideline, a quasi-millimetre-wave BPF is designed and implemented in a standard 0.13 μmu;mu;m bipolar complementary-metal-oxide semiconductor technology. The measured results show that the developed BPF device has a centre frequency of 28 GHz with a 3 dB fractional bandwidth of 21% and minimum in-band power-insertion-loss level of 3.4 dB. The stopband suppression is higher than 25 dB beyond 45 GHz. The chip size, excluding the pads, is only 0.017 mm2 (0.06 × 0.284 mm2).
