| 摘要 |
The invention relates to a current mirror keeping correct characteristics when the current to be copied corresponds to a voltage close to the lower power supply voltage Vss.
<??>This current mirror (1, T1, 2, T2) comprises a voltage feedback circuit (T5, T6, 10) which makes the first transistor (T1) of the reference arm of the mirror copy, in voltage, the second transistor (T2) of the output arm of the mirror.
<??>Applications to circuits functioning at low power supply voltages.
