Abstract
An operational amplifier (10) having an inverted output (20) ranging from a return voltage up to a rail supply voltage includes an amplifying stage (12) and: a linear output inverter (14). The linear output inverter (14) includes an inverting pull down stage (16), an output stage controller (17), and a pull up output stage (18). The inverting pull down stage (16) operates to pull the inverted output down to the return voltage when the inverted output is below a first threshold. The pull up output stage (18) operates to pull the inverted output up to the rail voltage when the inverted output (20) is above a second threshold. The first threshold is greater than the second threshold such that both the inverting pull down stage (16) and the pull up output stage (18) operate when the inverted output (20) lies between the first threshold and the second threshold.
