Differential amplifier circuit with a high through put rate and reduced power consumption |
摘要 |
A differential amplifier achieving a high throughput rate with reduced power consumption includes a differential circuit, output circuit, a constant current source transistor, a drive transistor, and a switching circuit. A difference voltage relative to a difference between voltages applied to non-inverting and inverting inputs of the differential circuit is applied to the switching circuit. The switching circuit supplies a drive signal to the drive transistor to enable the drive transistor when the difference voltage is below a predetermined threshold voltage, and to disable the drive transistor when the difference voltage is above the predetermined threshold voltage.
