Abstract
First and second differential transistor pairs, where each may be intentionally unbalanced or balanced, are provided. First and second variable current generators are coupled to control respective tail currents of the first and second differential pairs. A switch circuit is coupled to equalize the voltages of the respective tail current nodes. Applications of the amplifier circuit include sense amplifiers and comparators.
