Document Type and Number:
WIPO Patent Application WO/2019/173962
Kind Code:
A1
Abstract:
An anti-aliasing filter, a related device, and an anti-aliasing filter control method. The anti-aliasing filter comprises a power supply V, an adjustable resistor R1, a capacitor C1, an inductor L1, an adjustable capacitor C2, and a resistor R2. The negative electrode of the power supply V is grounded, and the positive electrode of the power supply V is coupled to a first end of the adjustable resistor R1; a second end of the adjustable resistor R1is coupled to a first end of the capacitor C1; a second end of the capacitor C1is grounded; a first end of the inductor L1is separately coupled to the first end of the capacitor C1and the second end of the adjustable resistor R1, and a second end of the inductor L1is coupled to a first end of the adjustable capacitor C2; a second end of the adjustable capacitor C2 is grounded; a first end of the resistor R2 is coupled to the first end of the adjustable capacitor C2 and the second end of the inductor L2, and a second end of the resistor R2 is grounded. The present application decreases the number of components, thereby reducing costs and power consumption.
