ABSTRACT:
A pair of self-biased differential amplifiers having a non-symmetrical topology are combined to provide a self-biased differential amplifier having a symmetrical topology. Each of the combined differential amplifiers includes a pair of transistors coupled to each other as a current mirror. The current mirror transistors are coupled in series with a respective one of a pair of differential input transistors. A current source transistor is coupled to the differential input transistors, and it is self-biased by one of the current mirror transistors.
