“…The Chebyshev BPF has inferior selectivity due to the poor stopband rejection level. To improve selectivity in wide bandwidth, techniques of introducing transmission zeros to increase stopband by adding shunt capacitor, serial inductor, or shunt inductor have been presented [22][23][24][25]. The active BPF proposed in this research is shown in Figure 10.…”

A classic second-order coupled-capacitor Chebyshev bandpass filter using resonator of tunable active capacitor and inductor is presented. The low cost and small size of CMOS active components make the bandpass filter (BPF) attractive in fully integrated CMOS applications. The tunable active capacitor is designed to compensate active inductor's resistance for resistive match in the resonator. In many design cases, more than 95% resistive loss is cancelled. Meanwhile, adjusting design parameter of the active component provides BPF tunability in center frequency, pass band, and pass band gain. Designed in 1.8 V 180 nanometer CMOS process, the BPF has a tuning frequency range of 758-864 MHz, a controllable pass band of 7.1-65.9 MHz, a quality factor of 12-107, a pass band gain of 6.5-18.1 dB, and a stopband rejection of 38-50 dB.

“…These CMOS BPFs operate above K-band because of loss considerations of transmission lines or inductors. Recently, a filter with a shunt-feedback inductor between input and output to generate three transmission zeros was successfully verified [29]. The shunt-feedback inductor topology contributes an additional transmission zero in the upper stopband compared with a shunt-feedback capacitor topology.…”

Abstract-In this paper, a second-order Chebyshev active bandpass filter (BPF) with three finite transmission zeros is presented. The filter utilizes a tapped-inductor feedback technique to compensate resistive losses of on-chip inductors, and a shunt-feedback inductor between input and output ports to achieve the transmission zeros. Moreover, one transmission zero is in the lower stopband, and two transmission zeros are in the upper stopband, thus improving the selectivity of the filter significantly. The filter is designed and fabricated in a standard 0.18-µm CMOS technology with a chip area of 0.57 mm × 0.65 mm including all testing pads. The circuit draws 6 mA from a 0.7-V supply voltage. Additionally, the filter achieves a 1.65-dB insertion loss and 13.2-dB return loss with a 17% 3-dB bandwidth at 23.5 GHz. The measured NF and input P 1 dB is 6.7 dB and −3.5 dBm. The rejection levels at the transmission zeros are greater than 15.2 dB. Finally, the large-signal characterizations are also investigated by the 1-dB compression point (P 1 dB ) of the filter.
