This letter proposes an entirely new method for performing analogue signal filtering. All circuits are based upon current amplifiers but derived from well-known voltage amplifier circuits. These circuits possess the same sensitivity properties as their voltage amplifier counterparts. However, it is expected that these circuits will operate at higher signal bandwidths, with greater linearity, and have larger dynamic range than their voltage-based circuit counterparts.
