A Design Of High-Speed And Gain-Boosted CMOS Operational Transconductance Amplifier
Zhang Xiang-zhen · China Integrated Circuit · 2007
The paper designs a cmos fully-differential operational amplifier of high-speed and high-resolving ADC, with gain-boosted telescopic cascode to get high unity gain bandwidth. With the 3.3 V power supply and in TSMC 0.35um CMOS mode achieved the dc open-loop gain of 110 dB with 315 MHz unity gain bandwidth ,2V output swing ,10mW power consumption and 65 phase margin though the Spectre simulator of Cadence software.
