Abstract
Provided is a an electronic system (1) comprising a plurality of sub blocks (21, 22, . . . ), a differential amplifier (3), a voltage regulation loop comprising a first transistor (40) and a variable resistor (5), and a plurality of additional transistors (41, 42, . . . ). The input reference voltage (VRF) and the variable resistor are configured such that a first sub block (21) is supplied with its required power supply output voltage (VDD1) by the transistor to which it is connected. The amplifier is configured to output on each of its outputs a power supply reference voltage (VG1, VG2 . . . ) such that each sub block (22, . . . ) other than the first sub block is supplied with its required power supply output voltage (VDD2 . . . ) by the transistor to which it is connected.
