| description | A current regulator circuit to improve electromagnetic compatibility performance operation of an IC device includes an input to receive a regulated voltage signal, an output to provide an output voltage at a desired voltage level, the output voltage exhibiting noise from a load, a first field effect transistor FET including a first source electrode coupled to the input, a first drain electrode coupled to the output, and a first gate electrode, a voltage clamp circuit coupled to the output, the voltage clamp circuit configured to conduct a varying current based upon the noise, a constant current source to provide a constant current, and a second FET including a second source electrode coupled to the output, a second drain electrode coupled to the constant current source and to the first gate electrode, and a second gate electrode coupled to the voltage clamp circuit to mirror the varying current in the second FET. |
