## Active -R filters are designed using intemully compensated operational amplifiers (OA) and resistors only. A one-pole or 6 dB roll ofi model for the PA's is assumed in these designs. This model is adequate for active-RC filters. However, for active-R filters such an assumption leads to serious
state-variable technique is employed in the realization of a multifunctional active-C biquadratic filter. The basic block is shown to give simultaneously low-pass (LP), band-pass (BP) and band-elimination (BE) responses. The use of only two operational amplifiers (OA's) and ratioed capacitors makes
