<p>PURPOSE:To prevent the booster from deteriorating due to the substrate effect and to realize driving with a low power supply voltage. CONSTITUTION:The substrate parts of transistors Qa,...,Q9 are isolated electrically from each other and connected with the source terminals N3,...N12 of respective transistors Q1,...,Q9 thus fixing respective substrate parts at the source potential of the transistors Q1,...,Q9. The transistors Q1,...,Q9 are driven with a clock signal phi2A or phi2B having an amplitude larger than that of a power supply voltage Vdd.</p> |
