A CMOS fully balanced four-terminal floating nullor

This paper presents design and implementation of a CMOS fully balanced realization of the four-terminal floating nullor (FTFN). The proposed fully balanced FTFN (FBFTFN) is an essential building block for implementing fully balanced architectures of both voltage and current-mode analog CMOS integrated circuits (ICs). A low-power class AB CMOS realization of the proposed circuit is fabricated in a 1.2-mum technology. The proposed circuit has numerous applications. Several applications including fully balanced amplifiers, filters, and sinusoidal oscillators are presented. All proposed design techniques and circuits are experimentally verified.
