A novel very-high-output-impedance high-swing cascode stage and its applications

Abstract

A "Super-MOS" maximum output swing CMOS/BiCMOS cascode circuit for use as a basic building block of low-voltage small geometry integrated circuits (on the order of 1 micron and smaller) is described. The described circuit provides a high output impedance and maximum output voltage swing capability. Its applications to a current mirroring circuit and to a VHF OTA are discussed.
