ABSTRACT:
An oscillation inducing circuit includes a power-on circuit connected to a power supply of V.sub.DD, a plurality of transfer gates, and a capacitor. The power-on circuit (1) supplies a control signal having a first level to the transfer gates so that a capacitor is charged in a first polarity direction to an instantaneous level of the increasing power supply voltage, and (2) supplies a control signal having a second level so that the capacitor is charged in a second polarity direction, opposite to the first direction, to a voltage equal to an addition of the previously charged voltage and the present instantaneous power supply voltage. Together, these two charges produce a relatively high voltage for initializing the circuit and starting an oscillator.
