Abstract
An amplifier comprising a main branch amplifier and an auxiliary branch amplifier, wherein one branch is a constant current-biased branch, and another branch is a voltage biased branch, with the branches connected in predetermined configurations to form a load modulated amplifier.
Claims13
A dual-stage amplifier comprising:
- a first transistor in a first stage biased using a current source;
- and
- a second transistor in a second stage biased using a voltage source and an output of the first stage being connected to an input of the second stage to form said dual-stage amplifier.
A dual-branch active cell comprising:
- a first transistor in a first branch biased using a current source;
- a second transistor in a second branch biased using a voltage source;
- and
- a combiner coupling an output of the first branch to an output of the second branch for combining RF signals and decoupling DC signals of biasing.
