Title:
ANALOG FRONT-END CHIP, ANALOG FRONT-END CIRCUIT, AND SIGNAL PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/016725
Kind Code:
A1
Abstract:
Embodiments of the present application provide an analog front-end chip, an analog front-end circuit, and a signal processing device. The analog front-end chip comprises: a first operational amplifier module, configured to perform amplitude adjustment on an electric signal on a path connected to a first input impedance network; and a second operational amplifier module, configured to perform amplitude adjustment on an electric signal on a path connected to a second input impedance network, wherein the impedance of the second input impedance network is different from that of the first input impedance network, and the first operational amplifier module and the second operational amplifier module are integrated in a same chip.
