چکیده
This paper presents the design and analysis of high speed, high gain and fully differential operational transconductance amplifier (OTA) implemented in 65-nm digital CMOS process. The OTA, which employ a folded-cascode topology with gain boosting technique, has rail-to-rail input swing and large output swing. The result shows the DC gain of 82 dB and a unity-gain frequency of 477MHz with phase margin of 59° (double 1-pF load) while consuming 4.8 mW. For the normal corner, the settling time to < 0.05% accuracy is 10 ns. KeywordsCMOS integrated circuits; OTA; gain-boosting
