VOLTAGE SUPPLY UNIT AND METHOD FOR OPERATING THE SAME

摘要

A voltage supply unit includes a regulator unit, a current mirror, and a cascode unit. The regulator unit is configured to receive first and second voltage signals and generate a third voltage signal. The current mirror is configured to generate first and second current signals based on the third voltage signal. The cascode unit includes a first terminal configured to receive the first current signal, a second terminal configured to receive a first bias voltage signal, a third terminal configured to receive a second bias voltage signal, and a fourth terminal electrically connected to the regulator unit. An output voltage supply signal is controlled by the second current signal.
