Title:
POWER SUPPLY NETWORK CAPABLE OF SWITCHING LOOP GAINS, SIGNAL PROCESSING SYSTEM, AND APPLICATION
Document Type and Number:
WIPO Patent Application WO/2021/174797
Kind Code:
A1
Abstract:
A power supply network capable of switching loop gains, a signal processing system, and an application. The power supply network is used for providing a bias signal to a power amplifier, and comprises a first filter circuit (1), a second filter circuit (2), and a switch (3). The first filter circuit (1) is always in a working state, and the state of the second filter circuit (2) is controlled by the on or off of the switch (3), so that the second filter circuit (2) forms a filter circuit having a resonant frequency different from that of the first filter circuit (1), so as to eliminate different loop gains. According to the power supply network, the state of the filter circuit working in the power supply network can be changed by means of the on or off of the switch, thereby achieving different resonant frequencies which can correspond to two frequency bands having relatively high loop gains in different frequency circuits, thereby achieving different loop gain characteristics, and use of one network can improve the stability of two frequency bands.
