| 摘要 |
The transistor threshold extraction circuit in accordance with the present invention has an output (OT) and comprises: a) at least two transistors (M1, M2) of the same type having respectively two control terminals (G1, G2) and having essentially the same threshold with each of said two transistors (M1, M2) also having a first (S1, S2) and a second (D1, D2) main conduction terminal, b) a current mirror (MC) having at least two input-output terminals (IM, OM) with said two terminals (IM, OM) coupled respectively to said two transistors (M1, M2) so as to supply to them the bias currents, c) a voltage generator (VG) connected between said two control terminals (G1, G2), and d) a feedback path (FP) between said control terminals (G1, G2) and one (OM) of said input-output terminals. The output (OT) is coupled to one (G2) of said control terminals. <IMAGE> |
