Abstract :
Design and implementation of a VLSI current mode continuous-time adaptive filter is described. The simplicity of the Laguerre approximation proposed allows operation at high frequencies. A bandpass adaptive filter with central frequency at 10 MHz and quality factor of ten, demonstrates the feasibility of the proposed approach.
