The proposed circuit is based on the current-mirror OTA topology. In addition, several circuit techniques are adopted to enhance the voltage gain. Simulated from a 0.8-V supply voltage, the proposed OTA achieves a 62-dB dc gain and a gain-bandwidth product of 160 MHz while driving a 2-pF load. The OTA is designed in a 0.18-μm CMOS process. The power consumption is 0.25 mW including the common-mode feedback circuit. © 2007, IEEE. All rights reserved. |
