摘要：

A novel building block is described, termed FCS (floating current source), which may serve as class A output stage for CFAs (current-mode feedback amplifiers). It is capable of driving a grounded load with a bipolar signal, and yields a feedback current equal to the output current over a wide frequency range. Its possible range of application covers MOSFET amplifiers employed in analog signal processing and current-operated control systems. An internal interconnection converts the FCS into a CCII-. Another novel CCII- configuration employs a push-Pull folded cascode and may serve as noninverting input stage for a standard amplifier configuration. Finally, a feedback-stabilized CCII- and a CFA are described, both employing the FCS as output stage.
