<p>The generator has three P-channel and two N-channel metal oxide semiconductor (MOS) transistors (P1-P3, N1, N2) connected in a current mirror assembly (41). One of the N-channel transistors is connected in series with a third N-channel MOS transistor (N3R) connected with a fourth N-channel MOS transistor (N4). The third transistor functions in its linear area, where a value of generated current is a function of an equivalent resistor of the third transistor. A channel of the third and fourth transistors is long such that ratio between length and width of the channel is greater than ten. An independent claim is also included for a voltage regulator comprising an operational amplifier.</p> |
