ABSTRACT:
A voltage regulation circuit intended to generate a regulated voltage for an electronic device, comprising: a transconductance amplifier based on a pair of MOS type differential amplifiers, said amplifier having a first input onto which a reference potential is applied and a second input onto which a counter reaction of said regulated voltage is input; a follower stage connected to the output from said transconductance amplifier; a MOS type transistor that will be used to make the output stage of the regulation circuit with a source connected to a first power supply potential. The transconductance amplifier comprises a resistive load360with a profile in K/gm, where gm is the transconductance coefficient of said input differential pair, said resistive load being connected to said first power supply potential.
