Abstract
An MOST buffer circuit has a first normally non-conductive transistor in series with a second normally conductive transistor between earth and a main power supply. A normally discharged bootstrap capacitor is connected between the common connection point of the two transistors and the gate of the first transistor. In response to an input signal, the transistor is switched on, the transistors conduct in series, and the bootstrap capacitor charges. The transistor is then switched off, ceasing the series current and developing an output potential which approximates to that of the power supply.
