This paper presents a circuit that improves supply noise rejection using an active inductor circuit. Compared to the conventional designs, the proposed supply noise suppression circuit has better characteristics such as low current consumption and small die size with noise rejection. The circuit was fabricated using 0.13 µm UMC CMOS technology. The experimental results showed that the supply noise was suppressed by 61% with only an increase in size of 20.0 µm 2.5 µm, and the current consumption was under 2 mA.
