Abstract :
This paper describes an implementation of a low-voltage CMOS buffer employing a negative feedback to improve its performance. Floating-gate transistors are incorporated to obtain low-threshold transistors and to increase the input/output voltage swing of the circuit operating at 1.2V. The designed circuit is fabricated in 0.5mum CMOS process, and occupies 0.0214mm2. It achieves total harmonic distortion (THD) of 48dB for 10kHz 0.6Vpp sinusoidal input signal
