Abstract
Methods and devices are provided for circuits. One device includes an adjustment circuit having an adjustable resistor for modifying a resistance value of a resistive device, the adjustment circuit connected to an adjustment terminal of the resistive device. The resistance value of the adjustable resistor changes, when a voltage or charge on the adjustment terminal of the adjustable resistor is changed. The adjustable resistor is a phase change element with an adjusting terminal to which different voltage values are applied for adjusting a conversion device threshold value.
Claims20
A system comprising:
- a plurality of devices of a circuit for performing a function associated with the circuit;
- and
- a temperature compensation selection module for receiving one or more temperature signals from a temperature sensor module that senses temperature values that are used to select different devices by the temperature compensation selection module to compensate for any changes in performing the function associated with the circuit caused by changes in temperature.
A system comprising:
- a plurality of devices of a circuit for performing a function associated with a circuit;
- a sample and hold circuit;
- and
- a temperature compensation module for receiving one or more temperature signals from a temperature sensor module that senses temperature values that are used to compensate for changes in performing a function associated with the circuit caused by changes in temperature;
- wherein adjustments are made to scaling of the sample and hold circuit to provide a non-unity gain based on compensation information to compensate for any changes in performing the function associated with the circuit.
A system comprising:
- a plurality of devices of a circuit for performing a time interleaved analog to digital conversion;
- and
- one or more compare modules that convert an analog signal to one or more digital signals;
- wherein the circuit includes a conversion time input and a conversion time adjustment for changing an analog to digital conversion time of the one or more compare modules and changing a number of the one or more compare modules, time interleaved, based on compensation information;
- wherein the number of compare modules time, interleaved, compensates for conversion time changes.
A method of temperature compensation in a circuit, comprising:
- performing a function associated with the circuit by a plurality of devices in the circuit;
- obtaining one or more temperature values by a temperature compensation selection module;
- selecting a different subset of devices from the plurality of devices by the temperature compensation selection module to compensate for a change in performing the function associated with the circuit caused by a change in the one or more temperature values.
