Problems solved by technology
[0002] With the development of nano-scale CMOS technology, the performance of digital circuits has been greatly improved, but it poses challenges to the design and reliability of radio frequency and analog circuits.
RF low-noise amplifiers and power amplifiers require an optimized matching impedance, but due to changes in the environment and the process angle of the circuit itself, the optimal matching impedance will change, and the fixed design cannot make the circuit work in the best matching state all the time

The invention relates to an on-chip matching self-repair system based on radio frequency analog circuit design, which optimizes the impedance matching network by measuring the characteristics of the circuit on the chip. The system includes an on-chip signal transceiver unit and two on-chip adjustable matching network units. The on-chip signal transceiver unit includes a signal transmitting link unit and a signal receiving link unit. The on-chip adjustable matching network unit includes an inductor-capacitor matching network and two voltage peak detection unit. By setting the matching network to be adjustable, the real-time detection of the voltage peak detection unit and the signal analysis of the digital signal processing system enable the matching network to be adjusted within a certain range with changes in factors such as the environment and process angle, and realize on-chip radio frequency The impedance matching of the circuit is self-healing.
Description
technical field [0001] The invention relates to the field of impedance matching optimization control of radio frequency analog circuits, in particular to an on-chip matching self-repair system. Background technique [0002] With the development of nano-scale CMOS technology, the performance of digital circuits has been greatly improved, but it poses challenges to the design and reliability of radio frequency and analog circuits. RF low-noise amplifiers and power amplifiers require an optimized matching impedance, but due to changes in the environment and the process angle of the circuit itself, the optimal matching impedance will change, and a fixed design cannot keep the circuit working in the best matching state. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention proposes an on-chip matching self-repair system, which can realize the impedance matching self-repair of the on-chip radio frequency circuit by evaluating the c...
