Weba supply voltage of +/- 1V. B. Common Mode Feedback Circuit (CMFB) Fig. 2. shows the block diagram of the common mode feedback circuit (CMFB) required for the fully differential OTA structure. CMFB circuit performs three operations: it senses the common mode outputs of the fully differential OTA then compares the result with a 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.
