Patent ID: 11921952
Assignee: NOVATEK MICROELECTRONICS CORP.
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A signal processing circuit, comprising:
a driving signal generator, configured to generate a driving signal;
an encoder, coupled to the driving signal generator, comprising:
a multiplexer, configured to receive a plurality of sensing signals through a plurality of sensing terminals in response to the driving signal;
a plurality of driver/receiver circuits, coupled to the multiplexer, comprising:
a first driver/receiver circuit, configured to output the driving signal, receive at least one first sensing signal among the plurality of sensing signals, and apply a first gain to the at least one first sensing signal to generate a first encoded signal; and
a second driver/receiver circuit, configured to output the driving signal, receive at least one second sensing signal other than the at least one first sensing signal among the plurality of sensing signals, and apply a second gain to the at least one second sensing signal to generate a second encoded signal, wherein the second gain is different from the first gain; and

a summation circuit, coupled to the plurality of driver/receiver circuits, configured to sum up the first encoded signal and the second encoded signal to generate an encoded data.
