摘要：
The realization of the second-order universal (low-pass, band-pass, high-pass, band-reject, and all-pass) active current filter using a single operational transconductance amplifier (OTA), two grounded capacitors, and one resistosr is proposed in this paper. Three input signals and the tunable tranconductance of the OTA determine the five generic filtering output signals. H-Spice simulations with 0.35 mu m process are used to validate the theoretical predictions of the filtering output signals, and show the low sensitivitie, and the sensitivity frequency responses.
