A programmable control circuit is disclosed for generating a programmable power curve and ramp. The circuit includes an amplifier having both positive and negative feedback. The positive feedback including a time lag component and the negative feedback including a gain component. The circuit output is easily programmable by varying the component values and/or the input signal. In one embodiment, the rate of change of the control circuit's output waveform may be modified. In another embodiment, the circuit controls the start-up power supplied to a load. In yet another embodiment, the circuit is a waveform generator. |
