Abstract

The invention discloses a low-voltage class-E power amplifier, a method, a chip and equipment, and belongs to the technical field of integrated circuits. The low-voltage class-E power amplifier comprises a driving stage module which is used for pre-ampligying a differential input signal; a power stage amplification module which is used for amplifying the differential input signal; and an inter-stage matching module which adopts a transformer structure and is used for carrying out matching connection on the driving stage module and the power stage amplification module. According to the application, the power levels of the driving signal and the output signal are ensured, high efficiency is realized under the condition of low-power work, and the difficulty of load loop design is simplified.Through the differential structure, common-mode signals can be effectively suppressed, noise is reduced, and linearity is improved.

Description

technical field [0001] The present application relates to the technical field of integrated circuits, in particular to a low-voltage Class E power amplifier, method, chip and equipment. Background technique [0002] In recent years, with the rapid development of radio frequency integrated circuit technology, many wireless communication products are used in daily life, and the ever-increasing requirements of low power consumption, low cost and portability put forward higher standards for the design of these wireless communication products. At present, there have been many successful cases of integrating single-chip RF transceivers using CMOS (Complementary Metal Oxide Semiconductor) technology, but integrating high-performance power amplifiers (Power Amplifier, PA) on the front-end chip of RF transceivers is still a huge challenge. Because the power amplifier has high output power, it occupies most of the power consumption in the whole system, so the power efficiency of the p...
