  • Publication number: 20240223199
    Abstract: A system and method for compensating segmented DAC intrinsic INL by adjusting the relative strength of DAC thermometer segments. In the method, the strength of each thermometer segment is adjusted sequentially to reduce INL to 0 at one point on each thermometer code range. The strength of the binary section is also adjusted to further reduce INL while conserving output amplitude. The system includes a calibration circuit that senses the DAC differential output and compares it to an ideal output generated from the same DAC via dithering between 0 and a maximum code. The compensation scheme only performs a specific type of DAC compensation, specifically compensating for systematic non-linearity rather than for mismatch-induced non-linearity. The method can also be applied to calibrate a full thermometer DAC.

  • Publication number: 20240223208
    Abstract: A system and method for calibrating a digital-to-analog converter (DAC) device. The method includes tuning a second subset of one or more DAC segments to match a strength of a first subset of DAC segments wherein the first subset of DAC segments is of a strength nominally equal to that of the second subset of DAC segments. The process is iterative, and the second subset of DAC segments is associated with lesser significant bits than the bits associated with the first subset of DAC segments. The process is repeated to tune each of successive second subsets of DAC segments to corresponding successive first subsets of DAC segments in top-down order from a segment associated with a MSB input to a segment associated with a LSB input. In each case the first subset of DAC segments is of a strength nominally equal to that of the second subset of DAC segments.

  • Patent number: 12015510
    Abstract: A circuit includes at least three equally weighted drivers; a state variable generator; and an element selector. The latter is coupled to the drivers, has a first input from the generator, has a second input including a plurality of input thermometer-encoded data streams, and has an output of an equal number of thermometer-encoded output data streams supplied to the drivers. The element selector maps the second input to the output dynamically based on a value of the first input from the state variable generator, with an update rate that is no more than one half of a symbol-rate. A serializer is configured to provide serialized data at the symbol rate, with output coupled to one of the second input of the element selector and input of the drivers. The drivers have outputs that are combined to produce an output of the circuit at the symbol rate.

  • Patent number: 11687148
    Abstract: A system and method for supporting an interconnection of processor cores, each core with functional state monitors for monitoring operations of each processor core, the processor cores interconnected using a resistive network connected between two-terminal regions being embedded in the resistive network such that each terminal of a region may be connected by controllable resistors to one or both fixed rails or by controllable resistors to one or more intermediate nodes. The resistor values are configurable to provide indirect control of the voltages across each two-terminal region, allowing full dynamic control of voltages of the two-terminal regions in a range up to the full voltage between the two voltage rails, and where a management unit accesses the functional state monitors and controls the resistor values. Feedback from functional state monitors allow the operating frequency to extend down to arbitrarily low values and up to the limits imposed by the technology.

  • Patent number: 10948611
    Abstract: Absorbed ionizing particles differentially effect first and second acquiring circuit stages configured to respectively generate first and second acquisition signals. Each acquisition signal has a characteristic that is variable as a function of an amount of absorbed ionizing particles. A measuring circuit generates, on the basis of the first and second acquisition signals, a relative parameter indicative of a relationship between the variable characteristics. A computation of a total ionizing dose is made using a 1st- or 2nd-degree polynomial relationship in the relative parameter.

  • Patent number: 9634671
    Abstract: A pulse signal generator has an input receiving an initial pulse signal having an initial period, an oscillator generating an oscillator signal, a first stage and a second stage. The first stage is synchronized with the oscillator signal and configured to deliver a secondary pulse signal having a separation between successive pulses that is representative of an integer part of a division of the initial period by an integer N. The first stage further delivers an auxiliary signal representative of a fractional part of the division and containing, for each pulse of the secondary pulse signal, an indication of a time shift to be applied to the pulse taking into account the separation. The second stage is configured to receive the successive pulses and the corresponding time shift indications and generate successive corresponding pulses of an output pulse signal.
