Abstract
The invention relates to a circuit generating a voltage signal which is independent of temperature and has low sensitivity to variations in process parameters, comprising at least an output MOS transistor through which an output current flows, it being connected to a first voltage reference and having a gate terminal connected to a bias network, in turn connected between a second voltage reference and the first voltage reference. The circuit of this invention includes a bias network comprising at least first and second MOS transistors connected in a diode configuration, connected in series between said first and second voltage references, and connected to the second voltage reference through a current generator element having a thermal gradient that approximates the thermal gradient of a MOS transistor.
