POWER EFFICIENT COMPLEMENTARY AMPLIFIER AND METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18182439 titled 'POWER EFFICIENT COMPLEMENTARY AMPLIFIER AND METHOD THEREOF
The method described in the patent application involves receiving an input signal and transforming it into two different signals with specific common-mode voltages. These signals are then processed to adjust bias voltages accordingly before being amplified using specific types of amplifiers.
- The input signal is transformed into a first signal with a common-mode voltage equal to a first bias voltage and a second signal with a common-mode voltage equal to a second bias voltage.
- Peaks and valleys of the transformed signals are detected to adjust the bias voltages accordingly.
- The first transformed signal is amplified using an N-type cascode amplifier, while the second transformed signal is amplified using a P-type cascode amplifier.
