Abstract :
This paper presents a simple, low voltage CMOS OTA circuit based on two voltage buffer circuits. The simulated results of the proposed circuit with 0.18 μm CMOS technology show that it can operate with 1.2V supply voltage, and in less than 0.1% THD for 100kHz, 600mV peak-to-peak differential input signal voltage.
