【 摘 要 】

A voltage mode multifunction second order filter topology employing single current differencing buffered amplifier (CDBA) has been proposed in this paper. This topology can be used to synthesize low pass (LP), band pass (BP), and high pass (HP) filter functions with appropriate admittance choices. This configuration is a suitable choice for implementing filters with high quality factor. The demonstration of the proposed configuration is done through PSPICE simulations. The CDBA block is realized using CMOS 0.18μm technology. The simulation results are found in close agreement with the theoretical results.
