  • Constant current biasing circuit for linear power amplifiers
    Patent number: 7443246
    Abstract: A constant current bias approach that receives an input bias voltage and maintains a temperature independent constant current bias in a linear amplifier device. Integrated sense circuitry protects against unacceptable input voltages to guarantee bias stability. Fabrication in multiple semiconductor technologies and assembly into a single package allows for optimum cost and performance of DC bias and RF amplifier sections.

  • Bias control for reducing amplifier power consumption and maintaining linearity
    Publication number: 20060208796
    Abstract: A method and apparatus for biasing an amplifying device whereby the bias current tracks the input power or the power level of a control signal to thereby efficiently match the bias current with needs of the amplifying device. This method and apparatus overcomes the drawbacks of the prior art by biasing, not for maximum output power, but for the power level of the input signal or the control signal. In one embodiment a current conditioner operates in connection with the self adjusting biasing circuit to scale or adjust, potentially on an exponential basis, the biasing current for one or more amplifier stages. A cancellation current source may be configured within the bias circuit to cancel unneeded current to further minimize current consumption.

  • Circuit and technique for accurate and efficient power amplifier sensing
    Patent number: 6768382
    Abstract: In one exemplary embodiment, a sensing circuit for sensing an output power of a power amplifier comprises a biasing circuit coupled to a detection circuit. The biasing circuit feeds a base current to the power amplifier, and the detection circuit draws a mirror current of the base current. The mirror current is fed at a first node to each of an impedance circuit and a first FET, wherein a sense voltage is generated at the first node. In one exemplary embodiment, the first FET is activated when a beta parameter of the power amplifier decreases.
