WebSeparate CMFB scheme is used for both stages to set each output to well defined common mode voltage level, here is 600mV. The quiescent output voltage at nodes vop1 and von1 sets the quiescent currents in the second stage [1]. Look at the common mode picture as shown in Fig 3, at high frequencies, the 2. nd-stage compensation capacitor 2𝐶. 𝐶 WebMay 23, 2005 · The proposed CMFB circuit utilizes the inherent differential-pair existing in the opamps as the virtual ground common-mode voltage detector, thus providing a new approach for very low-voltage implementation of fully-differential opamps (instead of traditional two single-ended opamps operating in pseudo-differential mode) using…
Webvoltage. As a consequence, the CMFB circuit will produce a higher VCM output control voltage (assuming that VCMI is constant and provided by a bandgap circuit) forcing VGSP 1 to remain constant, thus compensating the VDD variation. Process and temperature variations have similar compensations through the negative-feedback loop.
