Abstract
The present disclosure relates to circuitry comprising: digital circuitry configured to generate a digital output signal; and monitoring circuitry configured to monitor a supply voltage to the digital circuitry and to output a control signal for controlling operation of the digital circuitry, wherein the control signal is based on the supply voltage.
Claims26
Circuitry receiving a voltage derived from a voltage supply for controlling one or more signal paths comprising a controller configured to receive:
- voltage data relating to said circuitry;
- and/or
- thermal data relating to said circuitry;
- and/or
- signal data from said one or more signal paths, wherein each signal path comprises a respective transducer driver,
- wherein the circuitry is configured to output control data to said one or more signal paths for controlling one or more characteristics of respective signals in said one or more respective signal paths, wherein the controller is a predictive controller for controlling, based on one or more of said received data, one or more characteristics of the respective signals in said one or more respective signal paths before they are output from their respective transducer drivers so as to mitigate or avoid an adverse voltage and/or thermal and/or signal condition relating to said circuitry.
3 more elements
Circuitry comprising:
- one or more signal paths, each of the one or more signal paths being configured to carry a signal for driving a load;
- controller circuitry configured to receive data from at least one of the one or more signal paths and to output control data to one or more of the one or more signal paths for controlling one or more characteristics of the signal carried by the one or more of the one or more signal paths;
- wherein each of the one or more signal paths comprises transducer driver circuitry.
Circuitry comprising:
- one or more signal paths, each of the one or more signal paths being configured to carry a signal for driving a load;
- controller circuitry configured to receive data from at least one of the one or more signal paths and to output control data to one or more of the one or more signal paths for controlling one or more characteristics of the signal carried by the one or more of the one or more signal paths;
- wherein the controller circuitry is configured to output control data to limit a signal power of the load associated with the one or more of the one or more signal paths and/or to delay a signal in one or more of the one or more signal paths and/or to cause attenuation of the signal carried by the one or more of the one or more signal paths.
