Abstract
A fully differential operational transconductance amplifier is presented in this paper with enhanced linearity and low transconductance, suitable for low-frequency Gm-C filters. This paper also proposes a new common-mode feedback scheme that presents low sensitivity to large differential voltage swings at the OTA outputs. The proposed OTA was employed in the design of a fully-integrated Gm-C low-pass filter with a cutoff frequency of 30kHz. The Gm-C filter was fabricated in a 0.35μm CMOS technology and presented a THD at the output less than 1% for input signals with differential amplitudes up to 3.2V.
