ABSTRACT:
An automatic trigger circuit including: a two-arm current mirror including a first arm connected between a DC electrical supply and a ground, the first arm including a first transistor including a first source connected to the DC electrical supply, a first gate, and a first drain connected to the first gate; a second transistor including a second gate connected to the DC electrical supply, a second drain connected to the first drain and a second source; a third transistor including a third drain connected to the second source, a third gate for receiving a first level reference voltage, and a third source; and a fourth transistor including a fourth drain connected to the third source and a fourth source connected to the ground; and a second arm connected between the DC electrical supply and the ground, the second arm including a fifth transistor including a fifth source connected to the DC electrical supply, a fifth gate connected to the first gate and a fifth drain; and a sixth transistor including a sixth drain connected to the fifth drain, a sixth gate for receiving a second level reference voltage, and a sixth source connected to the fourth drain. The third transistor is a floating-gate detection transistor.
