Abstract:
A switching circuit receiving a supply voltage, a reference voltage, a line carrying a negative voltage, and a control signal, the switching circuit capable of providing at an output a voltage alternatively equal to said reference voltage or to the voltage of said line in response to said control signal, comprising:a first MOSFET with a first electrode operationally connected to said line, a second electrode operationally connected to said output, and a control electrode;a second MOSFET with a first electrode operationally connected to said reference voltage, a second electrode operationally connected to said output, and a control electrode; anddriving means for driving the control electrodes of said first and second MOSFETs respectively to the supply voltage and to the voltage of said line or, alternatively, to the voltage of said line and to the supply voltage, in response to said control signal.
