Abstract:Discrete-time switched-capacitor filters have been in wide-spread used for a few years, for the realization of stable, accurate and high quality filters. This paper describes the design of a new 8-path pseudo switchedcapacitor LC bandpass filter and its command circuit made up by a ring voltage controlled oscillator (VCO) with 'XOR' gates. The proposed architecture presents the possibility of tuning over a frequency broadband allowing to sweep different channels with a high quality factor. This circuit is inte… Show more
