摘要:
A feedback generator of a reference current may include a differential amplifier having a first input for a reference voltage, and a second input for a feedback voltage and generating an output voltage. The feedback generator may also include a first conduction path including a feedback resistor with the feedback voltage applied thereon, and a first transistor controlled by the output voltage and forcing through the feedback resistor the reference current. The feedback generator may also include a second conduction path coupled to the differential amplifier and biasing the differential amplifier based upon the reference current.
