| Abstract(in English) | In this paper, we present an ultra-low voltage analog amplifier based on a folded cascode opamp using subthreshold operation. Using Rail-to-Rail operation, this circuit consists of n-type and p-type differential pair at input and cascade gain stage at output. We design and evaluate it by 0.18 μm CMOS process. As a result, bandwidth is 200 to 400 kHz @ 0.5V and power consumption is 16.35nW @ 0.5V. Thus, proposed circuit can be achieved 10-100 times faster operation than ultra-low power 2-stage opamp which is already designed. |
