  • Patent number: 9337834
    Abstract: A high-linearity CMOS input buffer circuit is provided for neutralizing non-linearity of follower circuits' transconductance and output impedance resulting from input signals' variation. In doing so, the linearity of CMOS input buffer is improved. The buffer circuit includes a CMOS input follower circuit, a linearity improvement circuit of follower transistor, a current source load, and a linearity improvement circuit of load impedance. The buffer circuit is fabricated in standard CMOS process, featuring low cost, simplicity and strong linearity at high frequency. It has wide applications in analog and hybrid analog-digital CMOS ICs requiring high linearity input buffer.
