Abstract:
A booster circuit for use with a power source, comprising:an output terminal;a transistor connected between the output terminal and the power source, the transistor having a gate;first means for turning the transistor ON and OFF in response to a digital input signal, the first means including a first capacitor which has a terminal that is connected to the gate of the transistor and which also has another terminal, a first inverter which receives the input signal and which has an output that is connected to the another terminal of the first capacitor, a clamping circuit which is connected to the power source, and a diode which is connected between the clamping circuit and the gate of the transistor; andsecond means for generating a boosted voltage at the output terminal, the second means including a second capacitor which has a terminal that is connected to the output terminal and which also has another terminal, and a second inverter having an input which is directly connected to the another terminal of the first capacitor and having an output which is directly connected to the another terminal of the second capacitor.
