Two stage fully differential OTA with CMFB and tunable output CM level
This video presents the analysis and design of a two stage fully differential OTA with CMFB for the output CM level. The tunable range of the output CM is about 500mV. The first stage of the OTA is a pseudo differential inverter based amplifier. The second stage is an nmos common-source amplifier with a pmos current source load that is controlled by a CMFB loop. Inside the CMFB loop, there is a current-mirror OTA, through which the output CM level can be controlled. An exemplary design in 40nm CMOS is demonstrated.
