  • Publication number: 20230400946
    Abstract: The present application provides a touch sensing circuit, which comprises a plurality of analog front-end circuits, a noise processing circuit, and a compensation circuit. The analog front-end circuits generate a plurality of output signals according to a plurality of sensing signals. The noise processing circuit is coupled to the analog front-end circuits and generates an average noise according to the output signals. The compensation circuit is coupled to the noise processing circuit and compensates the output signals according to the average noise. By applying the touch sensing circuit of the present application, the influence of common-mode noise may be suppressed and the sensitivity of sensing touches may be improved.

  • Publication number: 20230397235
    Abstract: Techniques pertaining to dynamic band selection in multi-link operation (MLO) with time averaged specific absorption rate (TA-SAR) information in wireless communications are described. An apparatus determines a resource allocation regarding one or more multi-link operation (MLO) bands. The apparatus then allocates at least one of a transmit (TX) power, a TX duty cycle and a modulation and coding scheme (MCS) rate in wirelessly transmitting in the one or more MLO bands to result in a TA-SAR that is no greater than a predefined limit.
