摘要:
The present level shift circuit has a first (I1) and a second (I2) input respectively for input of a first and a second voltage signal and an output (OT) and comprises:
a) a first transistor (Q1) having a control terminal (G1), a first (S1) and a second (D1) main conduction terminal identifying a main conduction path, and b) a second transistor (Q2) of the same type as said first transistor (Q1) and having a control terminal (G2), a first (S2) and a second (D2) main conduction terminal identifying a main conduction path. The first signal is applied essentially between said control terminal (G1) and said first terminal (S1) of said first transistor (Q1) and said second input (I2) is coupled with the control terminal (G2) of said second transistor (Q2). The currents flowing in the conduction paths of the first (Q1) and the second (Q2) transistors are mutually proportional and one made from the other. The output (OT) is coupled with the first terminal (S2) of the second transistor (Q2). The control terminal (G1) of said first transistor (Q1) is connected to a potential reference (GND). The first signal is applied essentially to said first terminal (S1) of said first transistor (Q1).
