Voltage boosting with inverters
A ‘tree’ of inverters is highly suitable for boosting a voltage. That in the diagram provides voltages that are whole multiples of the input voltage by clock-driven charging of capacitors. The voltage across the capacitors is added stage by stage to the input voltage. Here, integrated circuits, IC2–IC7, each containing six inverters are used. In each IC, except IC2, one of the inverters is connected in series with the parallel combination of the other five.
