This paper presents the performance comparison of two typical multiple loop feedback all-pole operational transconductance amplifier-capacitor (OTA-C) filters: inverse-follow-the-leader-feedback (IFLF) and leapfrog (LF) filters. Two fourth-order structures are analysed and compared in terms of sensitivity, maximum input signal, noise, and OTA nonideality effects on magnitude response. Simulation results obtained show that the LF structure is better than the IFLF structure in these four performances. The comparison is based on the realisation of the fourth-order Butterworth low-pass characteristic with 1 MHz cut-off frequency.
