Abstract :
A systematic-realisation technique of the 2nd-order active-R filter using an inherent amplifier pole is proposed. To realise such a filter it is shown that two operational amplifiers and three resistors are sufficient. Workede examples are given. The resultant filters are found to be suitable for high-frequency low-Q-factor applications.
