Abstract
Disclosed are a dual-path analog-front-end (AFE) circuit and a dual-path signal receiver characterized by high linearity. The dual-path AFE circuit includes a first reception circuit, a second reception circuit and a multiplexer. The first reception circuit is configured to generate a first analog input signal according to a reception signal in a first mode and configured to be coupled to a first constant-voltage terminal via a first switch circuit in a second mode. The second reception circuit is configured to generate a second analog input signal according to the reception signal in the second mode and configured to be coupled to a second constant-voltage terminal via a second switch circuit in the first mode. The multiplexer is configured to output the first analog input signal in the first mode and output the second analog input signal in the second mode.
