High resolution thermal imaging for electrical and optical characterization of electronic and photonic devices....exist.Specifically, in applying CCD-based thermoreflectance to SiGe-based heterojunction bipolar transistors, we show how temperature mapping can be used to spatially profile device current, including asymmetric behavior such as current hogging....

Thermoreflectance imaging of current dynamics in high power sige heterojunction bipolar transistors... They show that current hogging for a HBT with two emitter subcells can lead to one subcell carrying 81% of the total current
Reducing the sensation of electrical stimulation with dry electrodes by using an array of constant current sources... Dry electrodes are longer lasting but are more uncomfortable due to unequal current distribution (current hogging)....
1 high temperature linear operation of paralleled power mosfets... This fact, coupled with the normal variation of threshold voltage from one transistor to another, produces a current hogging phenomenon in parallel transistors at high temperature, where the transistor with lowest threshold voltage, through positive thermal feedback, carries all or most...
