A review of some of the most common applications of the resistive local common mode
feedback technique to enhance amplifier’s performance is presented. It is shown that this simple
technique offers essential improvement in open loop gain, gain-bandwidth product, slew rate,
common mode rejection ratio, power supply rejection ratio, etc. This is achieved without increasing
power dissipation or supply voltage requirements and with small additional silicon area and circuit
complexity. It is also shown that it is especially appropriate to improve amplifiers’ performance
in current fine-line submicrometer CMOS technology. Some of the applications discussed are GB
enhanced, class AB and super class AB operational amplifiers, gain boosted op-amps, bulk-driven
circuits, sample and hold circuits and power management circuits, among others. [--]
