Abstract
A system includes a component having a signal input and a power supply input, wherein the power supply input is in communication with a power supply. The system also includes a voltage probe connected between the power supply input and the signal input, wherein the probe injects a compensating signal into the signal input to compensate for variations in an output signal of the power supply over time.
Claims26
A system, comprising:
- a component having a signal input and a power supply input, wherein the power supply input is in communication with a power supply;
- and
- a voltage probe connected between the power supply input and the signal input, wherein the probe injects a compensating signal into the signal input to compensate for variations in an output signal of the power supply over time.
A system, comprising:
- a component having a signal input, a power supply input, and an electron source, wherein the power supply input is in communication with a power supply;
- and
- a voltage probe connected between the power supply input and the electron source, wherein the probe injects a compensating signal into the signal input to compensate for variations in an output signal of the power supply over time.
A system, comprising:
- a first component having a signal input, a signal output, and a power supply input, wherein the power supply input is in communication with a first power supply;
- a second component having a signal input and a power supply input, wherein the power supply input is in communication with a second power supply and wherein the signal input is connected to the signal output of the first component;
- and
- a voltage probe connected between the power supply input of the second component and the signal input of the first device, wherein the probe injects a compensating signal into the signal input of the first device to compensate for variations in an output signal of the second power supply over time.
A method of compensating for unwanted phase changes at an output of a device, the method comprising:
- sensing a time-varying component of a signal output from a power supply;
- and
- adding the time-varying component of the signal to an input signal of the device.
An apparatus, comprising:
- means for sensing a time-varying component of a signal output from a power supply;
- and
- means for adding the time-varying component of the signal to an input signal of a device;
- wherein the adding compensates for unwanted phase changes at an output of the device.
