Signal processing circuit with encoder for multiple sensing signals
A recently granted patent (Publication Number: US11921952B1) discloses a signal processing circuit designed to enhance signal processing capabilities. The circuit includes a driving signal generator, an encoder with a multiplexer receiving sensing signals, and multiple driver/receiver circuits applying different gains to generate encoded signals. A summation circuit combines these signals to produce encoded data. Each driver/receiver circuit features an operational amplifier connected to the driving signal generator and multiplexer, ensuring efficient signal processing.
Moreover, the multiplexer in the circuit is equipped with select circuits that selectively connect sensing terminals to driver/receiver circuits based on an encoding matrix. A decoder is included to decode the encoded data using an inverse matrix, generating sensing data. The circuit can be applied to touch sensing signals, with the driving signal simultaneously output to sensing pads. Additionally, the method associated with this circuit involves applying different gains to sensing signals, summing them up to create encoded data, and decoding it using matrices. This innovative signal processing approach offers potential applications in various sensor technologies, enhancing signal accuracy and efficiency in data processing.
