Differential amplifier and active load for the same |
摘要 |
The differential amplifier and an active load are provided. The differential amplifier includes a differential input section which is configured to generate a differential current according to a differential input signal; and an active load which is configured to generate a differential output signal according to the differential current. The active load includes first and second active load sections comprising a first negative feedback loop and a second negative feedback loop, respectively; and a common mode feedback section comprising a feedback current source which supplies a feedback current to the first active load section and the second active load section to form a common mode feedback path.
