THE WIDEBAND TUNABLE BANDPASS FILTER AND MULTI-BAND WIDEBAND TUNABLE BANDPASS FILTER USING IT

摘要

A tunable wideband bandpass filter that can digitally vary the center frequency and bandwidth of a signal to be filtered, and includes a plurality of switched-capacitor banks for varying capacitance and converting the center frequency and bandwidth into a digital signal, and a plurality of inductors provided for inductance to generate the center frequency, the plurality of switched-capacitor banks that may be integrated into a signal chip.
