Abstract:
A differential amplifier comprising:a. a power-supply terminal; b. a differential input stage including: i. a first load having a first load terminal connected to the power-supply terminal, a second load terminal, and a first-load control terminal; ii. a second load having a third load terminal connected to the power-supply terminal and a fourth load terminal; iii. a first input transistor having: 1) a first control terminal connected to a first differential input terminal; 2) a first current-handling terminal connected to the second load terminal; and 3) a second current-handling terminal; and iv. a second input transistor having: 1) a second control terminal connected to a second differential input terminal; 2) a third current-handling terminal connected to the fourth load terminal; and 3) a fourth current-handling terminal; c. a differential output stage including: i. a third differential input terminal connected to the second load terminal; ii. a fourth differential input terminal connected to the fourth load terminal; and iii. an output terminal connected to the first-load control terminal.
