Compensation for a second pole located at an internal node (107 and 108) of a two pole cascode differential amplifier (30) is accomplished by introducing a left half plane zero in the transfer function of the cascode differential amplifier (30). This is done by coupling a compensation capacitor (46,...http://www.google.fr/patents/US5406220?utm_source=gb-gplus-shareBrevet US5406220 - Pole/zero compensation in cascode amplifiers
