Abstract :
This paper presents a new configuration for linear MOS operation transconductance amplifier (OTA) based on a standard 0.25 mum CMOS technology. The proposed circuit combines two previously reported linearization techniques: source degeneration using MOS transistor and class AB linearization. Measured results show that the proposed circuit provides rail-to-rail differential input range. Total harmonic distortion of the proposed circuit is -60 dB at 5 MHz for 0.6-Vpp differential input voltage while dissipating only 25 muW from 1.25 V supply
