Abstract	In this paper, the modified CMOS operational transconductance amplifier (MOTA) with multiple output terminals is proposed. The design and CMOS realization of the continuous-time current-mode all-pole lowpass filter with the MOTA leapfrog structure are discussed. For this kind of fully integrated continuous-time filter, the circuit structure is simple and the design is convenient. Because of using the current as the active parameter, the circuit operates with larger signal bandwidths, better linearity, higher slew rate and larger dynamic range than voltage-mode circuits. Since the OTA and capacitor are grounded, the circuit is not sensitive to the non-integrated capacitor. The circuit preserves the low sensitivity to the element. The design example is given and simulated by using SPICE.
