  • Publication number: 20220337198
    Abstract: An amplifier circuit includes a first input stage with a differential input transistor pair and a second gain stage having an output node coupled to a load. A node in the first gain stage is coupled to the output node in the second gain stage. A feedback line couples the output node to the control node of a first transistor of the differential input transistor pair. Current mirror circuitry is coupled to a current flow path through a further transistor in the second gain stage and includes a sensing node configured to produce a sensing signal indicative of the current supplied to the load. The sensing signal at the sensing node is directly fed back to the control node of the first transistor of the differential input transistor pair to provide a zero in the loop transfer function that is matched to and tracks and cancels out a load-dependent pole.

  • Publication number: 20220334862
    Abstract: Disclosed herein is hardware for easing the process of changing the execution mode of a virtual machine and its associated resources. By adopting the hardware, it is possible to trigger a change in the execution mode in an automatic way, without software intervention, and without interfering with the execution of other virtual machines. In addition, in case an error has occurred for a virtual machine and it is detected, the hardware can be used to disable the resources associated with that virtual machine and generate notification of the completion this operation to other hardware, which will complete the reset of the virtual machine. By adopting the hardware, the execution mode change is simplified and offers configurability and flexibility for a system running multiple virtual machines.

  • Patent number: 11474788
    Abstract: A memory array arranged in multiple columns and rows. Computation circuits that each calculate a computation value from cell values in a corresponding column. A column multiplexer cycles through multiple data lines that each corresponds to a computation circuit. Cluster cycle management circuitry determines a number of multiplexer cycles based on a number of columns storing data of a compute cluster. A sensing circuit obtains the computation values from the computation circuits via the column multiplexer as the column multiplexer cycles through the data lines. The sensing circuit combines the obtained computation values over the determined number of multiplexer cycles. A first clock may initiate the multiplexer to cycle through its data lines for the determined number of multiplexer cycles, and a second clock may initiate each individual cycle. The multiplexer or additional circuitry may be utilized to modify the order in which data is written to the columns.

  • Patent number: 11474425
    Abstract: A control circuit includes a first control circuit generating a first drive control signal from a pre-drive signal (that is a frequency at which an opening angle of the first and second mirrors is equal) for the first mirror. A second control circuit generates a second drive control signal from the pre-drive signal for the second mirror. First and second drivers generate first and second drive signals for the first and second mirrors from the first and second drive control signals. The first and second drive control signals are generated so that the first and second drive signals each have a same frequency as the pre-drive signal but are different in amplitude from one another to cause the first and second mirrors to move at a same frequency, with a same and substantially constant given opening angle as one another, and in phase with one another.

  • Publication number: 20220327845
    Abstract: A time series of face images of a human during a human activity are captured. A first artificial neural network (ANN) processing pipeline processes the captured time series of face images to provide a first attention level indicator signal. An electrophysiological signal indicative of the level of attention of the human during the activity is also captured. A second ANN processing pipeline processes the sensed electrophysiological signal to providing a second attention level indicator signal. A risk indicator signal is then generated based on at least one of the first attention level indicator and second attention level indicator. A user circuit is then triggered as a result of the risk indicator reaching or failing to reach at least one attention level threshold.
