AMPLIFIER WITH IMPROVED, HIGH PRECISION, HIGH SPEED AND LOW POWER CONSUMPTION ARCHITECTURE

摘要

Amplifier has improved, high-precision, high speed, low power architecture, including input stage (1), intergrade and output stage (2) (3), intergrade (2) offer is that (2a complementary classes AB is operated by combination two half-unit, these drivings 2b) by Complementary input structure grade, then, one of class AB work, the half portion has lower limit current gain (GU), easily but it is not required control, one has high or very high current gain (GD), can with but to be not required be to control. It appropriately enters AB classes input stage (1) and amplifier offer two pairs or a pair of of an anti-phase output electric current (IR and IL) is provided, be easy to the intermediate stage for supplying two half-unit (2a, 2b).
