Abstract :
For applications requiring low distortion and low power and for low supply voltage environments, the multipath feed-forward compensation is an attractive design technique. It achieves high loop gain over a wide bandwidth without requiring any high speed amplifier stages or complex design equations. As a result it leads to low power solutions. This paper describes the design procedure to design stable amplifiers of arbitrary order with ease
