Abstract :
Three recently proposed grounded capacitor active filters using the amplifier pole have been compared. Some limitations of these circuits for realizing bandpass filters at low frequencies, due to the finite ωaof the operational amplifier, are discussed. These circuits are also compared with other input-capacitor based bandpass filters.
