  • Signal chain with embedded power management
    Patent number: 11652492
    Abstract: A system for processing a signal in a signal chain having decentralized embedded power management of components of the signal chain includes an input circuit to generate a measurement signal responsive to a stimulus, where the measurement signal is indicative of a characteristic of the stimulus. The system additionally includes a signal converter circuit coupled to the input circuit to convert the measurement signal to a digital signal according to a timing condition for capturing a sample of the measurement signal. The signal converter includes a control circuit to provide electrical power to the input circuit based on the timing condition and a sampling circuit to capture the sample of the measurement signal responsive to an indicator signal generated by the sensor circuit.

  • Digital compensation tuning for switching power supply control
    Patent number: 7876083
    Abstract: A tuner having one or more digitally controllable tuning components may be coupled to an analog feedback compensation network in a target switching power supply controller to adjust the compensation while the power supply is operating. A communication interface couples the tuner to a host having a software interface to enable a user to adjust the values of the tuning components. The tuner may include components to adjust the values of a feedback network, an input network, a ramp adjust component, etc., on the target controller.
