A new multifunction switched-current filter



A new switched-current (SI) biquadratic filter is presented which can simultaneously provide the low-pass, high-pass and band-pass filters in a single building block. A symbol to represent the univeral SI integrator is also introduced. It can simplify the analysis and synthesis of SI networks.
