Abstract
A voltage providing circuit includes a first circuit configured to receive a first input signal and a second input signal and to generate an output signal. The first circuit includes a first transistor configured to switchably couple the second input signal to a first node responsive to the first input signal, a second transistor having a gate terminal coupled with the first node, and a third transistor having a source terminal coupled with a source terminal of the second transistor. The third transistor is configured to set a reference voltage value at the source terminal of the second transistor if the first input signal indicates that the second input signal is pulled from a first voltage value toward a second voltage value and if the second input signal reaches a predetermined voltage value. A second circuit is configured to receive the output signal and to generate an output voltage.
