DIFFERENTIAL AMPLIFIER WITH AUTO BIAS ADJUST |
摘要 |
In a differential amplifier circuit a closed loop bias adjustment circuit samples the lower of the output levels of the differential amplifier output stages to control a variable current source. This variable current source draws current from the amplifier to bias the output transistors thereof to provide optimum speed, maximum voltage swing, and minimum power dissipation. |
