BIASING CONTROL FOR COMPOUND SEMICONDUCTORS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240045461 titled 'BIASING CONTROL FOR COMPOUND SEMICONDUCTORS
Simplified Explanation
The abstract of this patent application describes a compound semiconductor integrated circuit that includes biasing circuitry for generating a bias voltage at a bias output node. The biasing circuitry consists of a first circuit branch that extends between a defined voltage and a supply voltage. This first circuit branch includes a first transistor configured as a current source to generate a defined current and a controllably variable resistance. The bias output node is connected to the first circuit branch at a first node located between the controllably variable resistance and the first transistor. The biasing circuitry is designed to vary the resistance value of the controllably variable resistance with a control voltage, thereby varying the value of the bias voltage.
