Abstract
A differential amplifier with a positive input terminal, a negative input terminal, an output terminal, a bias terminal and a ground terminal has a differential pair circuit and a current mirror circuit. Wherein, the differential pair circuit is connected to the positive input terminal, the negative input terminal, output terminal and the bias terminal. The current mirror circuit receives a fixed current generated by a current source, and mirrors the fixed current to the differential pair circuit. In addition, the current mirror circuit is connected to the ground terminal, and the terminal of the current mirror circuit received the fixed current is connected to a first source/drain terminal of a first PMOS transistor. A second source/drain and a gate of the first PMOS transistor is connected to the bias and the output terminals respectively.
