Semiconductor integrated circuit |
摘要 |
An improved semiconductor integrated circuit included in electrical equipment for recharging and discharging a load capacitor with alternating current and which includes differentiating circuits inherently formed in the integrated circuit and whose devices are formed on a P-type substrate and are isolated from each other by PN junction isolation. The substrate of the integrated circuit is electrically isolated from any grounding electrodes and is connected to a negative voltage source.
