EnglishNew circuit solutions able to operate under sub-1V supplies must be developed by analog designer to counteract the low intrinsic gain and limited rejection to common-mode and power supply disturbances offered by nanometer CMOS technologies. In this communication, an approach originally developed as a common-mode control loop for body-driven amplifiers, is exploited in the active load of a source-coupled pair to remarkably improve its small-signal performance. Simulations on a 65-nm design supplied from 0.75V show a nominal increase in differential DC gain, CMRR and PSRR of 20 dB, 29 dB and 32 dB, respectively, as compared to the standard solution.
