ABSTRACT:
A slope control circuit having a plurality of resistive elements connected in parallel, each of the resistive elements including a control element for causing the associated resistive elements to be one of electrically conductive or electrically nonconductive, a delay circuit having a plurality of delay components coupled together in series, each of the delay components having a predetermined delay, the junction of each different adjacent pair of the delay components being coupled to the control element of a different one of the resistive elements and a load circuit coupled across the plurality of resistive elements. The circuit can further include a delay adjust circuit for adjusting the delay of each of the delay components, either initially or on-line. The resistance of each of the resistive elements can be the same or different. The plurality of resistive elements and the delay components are all disposed on a single semiconductor chip.
