Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] The memristor-based reconfigurable bandpass filter used in this embodiment is different from the reconfigurable methods in previous filters, and the following calculations and analyzes are based on a complete radio frequency filter structure.

[0021] Such as figure 1 As shown, the invention loads two memristors M1 and M2 on the basis of a dual-band bandpass filter. The invention mainly includes a dual-frequency band-pass filter, two memristors, and four single-pole double-throw switches; the 3 ports of the single-pole double-throw switch SPDT2 are loaded in the dual-frequency band-pass filter to generate a suitable position A of the low-frequency passband, and the SPDT2's Port 1 is connected to one end of the memristor M1 and port 2 of the SPDT1, the port 2 of SPDT2 is suspended; the other end of the memristor M1 is grounded; port 1 of the SPDT1 is u...

Abstract

The invention relates to a novel reconfigurable dual-band bandpass filter based on memristors. The invention introduces a memristor control circuit, which can effectively avoid the interference of the memristor control voltage on the overall circuit test. At the same time, the present invention proposes a radio frequency filter structure that uses a memristor with a wide tuning range as a basis and can realize reconfigurable passband of the filter by controlling and regulating the voltage. The loaded memristor has the advantages of low power consumption and excellent linearity at high frequencies, which caters to the development needs of modern radio frequency communication systems. The small size of the memristor brings advantages to reduce the overall circuit size, and the loaded memristor can realize the function of multi-mode switching in the radio frequency filter.

Description

technical field [0001] The invention belongs to the intersecting field of electronic information technology and memristor technology, and in particular relates to a radio frequency filter capable of realizing reconfigurable passband by adjusting a loaded memristor. Background technique [0002] With the rapid development of wireless communication technology in the 21st century, reconfigurable RF filters, as an indispensable part of the RF front-end, have received more and more attention from relevant researchers in recent years. At present, the reconfigurable method of RF filter is mainly to tune by devices such as varactor diodes, PIN diodes, and MEMS switches. Devices such as varactor diodes, PIN diodes, and MEMS switches can only adjust the center frequency or bandwidth of the filter, and the continuous power supply of the tuning devices will increase the power consumption of the overall circuit. Due to the scarcity of current spectrum resources, the spectral resources c...
