| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we present an ultra-low voltage 2-stage analog amplifier circuit using only subthreshold current. There are both n-type and p-type differential amplifier circuits at first-stage. At second-stage, simple output buffer circuit is connected from each outputs of first-stage. Thus, proposed circuit realizes high gain, wide input/output range and ultra-low current consumption. As a result of simulation with standard $0.18 \, \mathrm{\mu m}$ CMOS process, DC gain is $62.8 \, \mathrm{dB}$ and current consumption is $4.1 \, \mathrm{nA}$ at $0.4 \, \mathrm{V}$. The input/output range is $96.7 \, \mathrm{\%}$ of $0.4 \, \mathrm{V}$ by voltage-follower operation. |
