A very-high impedance, high-swing cascode stage for sub-micron analog VLSI

In this article we describe a novel sub-micron analog VLSI circuit which can be used as a cascode current source, current mirror, or transresistance stage amplifier with maximum output swing capability. The described circuit, which is also viewed as a "super-MOS" device, displays both gain-boosting and optimum biasing of the cascode stage for low-voltage applications.
