Abstract
The current comb generator periodically applies current spikes to a power supply signal in the time domain to produce a series of current spikes at different frequencies in the frequency domain.
Claims24
A current comb generator, comprising:
- a load;
- a voltage detector configured to detect if a power supply signal is at a particular voltage;
- and
- a switch configured to connect the load to the power supply signal and then disconnect the load from the power supply signal in response to the voltage detector detecting that the power supply voltage is at a particular voltage.
1 more element
A current comb generator, comprising:
- a load;
- an angle detector configured to detect if the power supply signal is at a particular angle;
- and
- a switch configured to selectively connect the load to a power supply signal for a period of time if the angle detector detects that the power supply signal is at the particular angle.
