Simple voltage amplifier

Simple voltage amplifier
The resistive nature of the complementary outputs of a eMDS logic inverter may be used to create a voltage gain stage which allows an output swing of almost the supply voltage. In the circuit shown, eMDS gates are used to extend an amplifier's output swing to almost 5 V. The circuit is particularly useful in 5-V powered analogue systems where improvements in available output swing are needed to maximize the signal processing range and drive margin.
