A - Enhanced Active - Bandpass Filter
A fully differential high-Q bandpass filter that uses lossy integrated inductors is presented. The circuit is implemented in a 0.8 m BiCMOS technology and realizes a center frequency of 750 MHz with a Q-factor that is tunable from 10 to 490 while dissipating 80–100 mW from a single 5 V supply. Since the objective of the prototype was to explore the proposed Qenhancement technique, the dynamic r...
متن کاملDesign of Low-loss and Highly-selective Cmos Active Bandpass Filter at K-band
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 trans...

متن کاملTunable Active Dual-Band Bandpass Filter Design Using MMIC Technology
Abstract— The inductor-less designing of monolithic tunable active dual-band bandpass filter is presented in this study. Biasing voltages signify main role. They can control the center frequency and quality factor. Using four biasing voltages and cascading two similar filters leads to dual-band bandpass filter. By keeping the gain constant, the center frequency shift is 200 MHz. Regardless cons...
متن کاملWide Tuning Range Active RF Bandpass Filter with MOS Varactors
The paper presents an improved tuning method implemented for a differential active inductor based RF bandpass filter. Derived from a previous designed transistor-only second order filter topology, independent frequency and quality factor tuning are demonstrated in 0.18 μm CMOS technology. The circuit has been basically designed for a maximum frequency of 2.4 GHz, high enough to cover the main w...
