Abstract
A self-biased cascade amplifier circuit includes first and second transistors connected in series and coupled between a dc voltage source terminal and a common terminal. An input signal terminal is coupled to a control electrode of the first transistor, and an output signal terminal is coupled to an output terminal of the second transistor. An integrated bias circuit is coupled between the dc voltage source terminal and the common terminal for internally biasing both the first and the second transistors without the use of an external bias supply or a direct bias connection to the dc voltage source. This arrangement provides a fully self-biased cascode amplifier circuit having improved performance and a simple and compact configuration.
