Abstract

We propose a current-mode analog programmable finite-impulse-response (FIR) filter with variable tap circuits. From the circuit simulation, the operation of the 7- tap FIR filter is confirmed. We design and fabricate the 0.0625-step tap circuit using 0.8$\mu\textrm{m}$ CMOS technology. The proposed FIR filter has a variable length of taps and variable coefficients, so it has a potential for being used to software defined radio (SDR) terminals.
