| Abstract: | A switched-current(SI) modified universal building-block(MUB) is proposed with low sensitivities as well as positive and negative outputs. Various basic operations of sampled-data signal processing can be performed by the MUB. Based on this building-block, a new SI high-Q biquadratic filter is generated from the switched-capacitor prototype by the means of signal flow graphes, which can obtain low-pass, high-pass, bandpass and band-reject filtering functions. |
