Abstract
A unity gain amplifier of the Diamond follower type provides the combination of negligible input offset voltage, high slew rate, and high bandwidth by providing first and second opposite polarity current mirror circuits which respond to currents flowing through first and second input transistors to boost current available to charge parasitic capacitances during fast rise times and fast fall times of an input pulse. The rapid charging and discharging of the parasitic capacitances eliminates degradation in the rise and fall times of an output pulse produced by the unity gain amplifier.
