Abstract
A voltage stabilizing circuit for chips and the method thereof are disclosed. The circuit and the method thereof are applied to chips with at least one non-wire bonded I/O circuit. The driver circuit of the I/O circuit includes a plurality of transistors. The method of voltage stabilizing involves causing at least one of these transistors to start conducting in order to generate a stabilizing capacitor. Therefore, chip damages caused by voltage or current fluctuations can be avoided, simultaneously reducing the cost and the amount of chip surface area being consumed.
