Injection lock power amplifier with back-gate bias
In an exemplary structure, a transformer has a primary side and a secondary side. Output from the primary side is coupled to the secondary side. A first power supply is connected to a center tap of the primary side of the transformer. An oscillator includes a first transistor and a second transistor. The front-gate of the first transistor is connected to the drain of the second transistor and the primary side of the transformer. The front-gate of the second transistor is connected to the drain of the first transistor and the primary side of the transformer. A third transistor is connected to the first transistor and a fourth transistor is connected to the second transistor. The third and fourth transistors inject a desired frequency to the oscillator. A voltage source is connected to the back-gate of the first transistor and the back-gate of the second transistor.
