Abstract :
An architecture for the switched-current (SI) realisation of complex filters is presented, based upon the signal flow-graph method. Also briefly discussed is a practical design flow for SI complex filters, based on that for traditional real SI filter designs. A verification of the architecture is given via the design and simulation of a fifth-order complex SI bandpass filter with 1 MHz centre frequency and bandwidth, implemented using a low-voltage class AB neutralised SI scheme
